The multiples of a number are all the numbers that are equal to the original number times another number. For example, 24, 36, 48 and 60 are all multiples of 12. 25 is not a multiple of 12 because there isn't any number that can be multiplied by 12 to get 25. If one number is a factor of a second number, then the second number is a multiple of the first number. Again, you can think of multiples as families, and factors are the people who belong to those families. The factor 5, has parents 10, grandparents 15, great-grandparents 20, great-great-grandparents 25, and every extra step of 5 is another great- in front! But the number 5 does not belong in the 8 or 23 families. You can't fit any number of 5s into 8 or 23 with nothing left over. So '8 isn't a multiple of 5, nor is 23. Only 5, 10, 15, 20, 25 ... are multiples (or families or steps) of 5. Use the arrow keys to navigate around the board and to avoid the Troggles. Press the spacebar to eat a number.
’S e a h-uile àireamh a bhios co-ionnan ris an àireamh tùsail air iomadachadh le àireamh eile a th’ anns na h-iomadan de àireamh. Mar eisimpleir, tha 24, 26, 48 is 60 uile nan iomadan de 12. Chan eil 25 na iomad de 12 oir chan eil àireamh ann leis am b’ urrainn dhut 12 iomadachadh gus 25 fhaighinn. Ma tha an dàrna àireamh na fhactar aig an àireamh eile, tha an àireamh eile na iomad dhen dàrna àireamh. A-rithist, ’s urrainn dhut beachdachadh air iomadan mar theaghlaichean is tha na factaran nan daoine a bhuineas ris na teaghlaichean ud. Leis an fhactar 5, is 10 a phàrant, 15 a sheanair, 20 a shinn-seanair, 25 a shinn-sinn-seanair le “sinn” a bharrachd aig toiseach gach ceum de 5! Ach chan eil 5 na bhall dhe na teaghlaichean aig 8 no 23. Chan eil àireamh de chòigean ann a b’ urrainn dhut cur ann an 8 no 23 gun dad air fhàgail. Mar sin, chan eil 8 no 23 na iomad de 5. Chan eil ach 5, 10, 15, 20, 15 ... nan iomadan (no teaghlaichean no ceuman) de 5. Cleachd na saighdean gus gluasad timcheall a’ bhùird is na bòcain a sheachnadh.
