Find LCM of 931,549,686,651,102 with Prime Factorization
| 2 | 931, 549, 686, 651, 102 |
| 3 | 931, 549, 343, 651, 51 |
| 7 | 931, 183, 343, 217, 17 |
| 7 | 133, 183, 49, 31, 17 |
| 19, 183, 7, 31, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 7 x 19 x 183 x 7 x 31 x 17 = 3771035982
Therefore, the lowest common multiple of 931,549,686,651,102 is 3771035982.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
931 x 549 x 686 x 651 x 102 = 23282376152868
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
931 : 1, 7, 19, 49, 133, 931
549 : 1, 3, 9, 61, 183, 549
686 : 1, 2, 7, 14, 49, 98, 343, 686
651 : 1, 3, 7, 21, 31, 93, 217, 651
102 : 1, 2, 3, 6, 17, 34, 51, 102
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 931,549,686,651,102, is 1.
Now, the common factors can be found like this.
931:7x 7x 19
549:3x 3x 61
686:2x 7x 7x 7
651:3x 7x 31
102:2x 3x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 7x 7x 7 = 6174
Therefore, the value for common factors is 6174.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 23282376152868/(1x6174)
LCM = 23282376152868/6174
LCM = 3771035982
Thus, we can understand that the LCM of 931,549,686,651,102 is 3771035982.
