Find LCM of 636,428,870,690,989 with Prime Factorization
2 | 636, 428, 870, 690, 989 |
2 | 318, 214, 435, 345, 989 |
3 | 159, 107, 435, 345, 989 |
5 | 53, 107, 145, 115, 989 |
23 | 53, 107, 29, 23, 989 |
53, 107, 29, 1, 43 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 23 x 53 x 107 x 29 x 1 x 43 = 9758997060
Therefore, the lowest common multiple of 636,428,870,690,989 is 9758997060.
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.
636 x 428 x 870 x 690 x 989 = 161608991313600
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.
636 : 1, 2, 3, 4, 6, 12, 53, 106, 159, 212, 318, 636
428 : 1, 2, 4, 107, 214, 428
870 : 1, 2, 3, 5, 6, 10, 15, 29, 30, 58, 87, 145, 174, 290, 435, 870
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
989 : 1, 23, 43, 989
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 636,428,870,690,989, is 1.
Now, the common factors can be found like this.
636:2x 2x 3x 53
428:2x 2x 107
870:2x 3x 5x 29
690:2x 3x 5x 23
989:23x 43
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 2x 3x 3x 5x 23 = 16560
Therefore, the value for common factors is 16560.
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 = 161608991313600/(1x16560)
LCM = 161608991313600/16560
LCM = 9758997060
Thus, we can understand that the LCM of 636,428,870,690,989 is 9758997060.
