1 x 98 = 98 2 x 98 = 196 3 x 98 = 294 4 x 98 = 392 5 x 98 = 490 6 x 98 = 588 7 x 98 = 686 8 x 98 = 784 9 x 98 = 882 10 x 98 = 980 11 x 98 = 1078 12 x 98 = 1176
1 x 98 = 98 2 x 98 = 196 3 x 98 = 294 4 x 98 = 392 5 x 98 = 490 6 x 98 = 588 7 x 98 = 686 8 x 98 = 784 9 x 98 = 882 10 x 98 = 980
2 x 7 x 7 = 98
27 = 3 x 3 x 3 98 = 2 x 7 x 7 There is no common factor other than 1.
2 x 3 x 5 x 7 = 210 2 x 7 x 7 = 98
2 x 7 = 14 2 x 3 x 7 = 42 2 x 7 x 7 = 98 2 x 3 x 7 x 7 = 294, the LCM
98 = 2 x 7 x 7; 105 = 3 x 5 x 7 so GCF = 7
Factor them. 2 x 3 x 7 = 42 2 x 7 x 7 = 98 Combine the factors, eliminating duplicates. 2 x 3 x 7 x 7 = 294, the LCM
14. 42 = 2 x 3 x 7 98 = 2 x 72 hcf = 2 x 7 = 14
The Greatest Common Factor of 154, 98, 42: 1414 (x 7, x 3 and x 11)
There are 100 centimetres in one metre. Therefore, 3 metres 98 centimetres is equal to (3 x 100) + 98 = 398 centimetres.
