They are 49+2 = 51
63
98
The factors of 42 are 1, 2, 3, 6, 7, 14, 21, 42 The factors of 98 are 1, 2, 7, 14, 49, 98
The factors of 42 are: 1, 2, 3, 6, 7, 14, 21, 42 The factors of 98 are: 1, 2, 7, 14, 49, 98 The common factors are: 1, 2, 7, 14
A number which has more than two factors is called composite number. 98 is a composite number because it has more than two factors. Factors of 98: 1, 2, 7, 14, 49 and 98. In order to prove that a number is composite try to find a factor other than 1 and the number itself: Since 98 is an even number so it is divisible by 2, so 2 is one of the factors of 98. For now we know three factors of 98: 1, 2 and 98. So, 98 is a composite number since we have found more than two factors.
2 x 7 x 7 = 98 The prime factors of 98 are 2 and 7.
The factors of 294 are: 1, 2, 3, 6, 7, 14, 21, 42, 49, 98, 147, 294
7 & 14 :d
2. there couldn't be anything else because 100-98=2. don't get that? what is the greatest common factor between 14 and 21? 7. right? 21-14=7. take the number 7 for example, if 98 and 100 are two digits away then they couldn't both be divisible by 7
