420
420 = 2940
2940
7 x 400 + 7 x 20 _________ 2940
1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 49, 60, 70, 84, 98, 105, 140, 147, 196, 210, 245, 294, 420, 490, 588, 735, 980, 1470, 2940.
The best way to do this is to factor both numbers. 2940 = 2 * 2 * 3 * 5 * 7 * 7 3150 = 2 * 3 * 5 * 5 * 7 Now take the ones that are common: 2 * 3 * 5 * 7. That's 210 to check, you can take the unused factors. For 2940 that's 2 * 7 = 14 and 14 * 210 = 2940 For 3150 that's 3 * 5 = 15 and 15 * 210 = 3150 The 14 and 15 also tell us we have it right since they share no common factors.
7 is not divisible by 104 and 104 is not divisible by 7.
Not only is 119 divisible by 7 but it is evenly divisible by 7.
The prime factors of 2,940 are: 2, 3, 5, 7
No it is not divisible by 7
9 + 2940 = 2949.
