Find LCM of 920,812,691,768,634 with Prime Factorization
2 | 920, 812, 691, 768, 634 |
2 | 460, 406, 691, 384, 317 |
2 | 230, 203, 691, 192, 317 |
115, 203, 691, 96, 317 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 115 x 203 x 691 x 96 x 317 = 3927284901120
Therefore, the lowest common multiple of 920,812,691,768,634 is 3927284901120.
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.
920 x 812 x 691 x 768 x 634 = 251346233671680
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.
920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920
812 : 1, 2, 4, 7, 14, 28, 29, 58, 116, 203, 406, 812
691 : 1, 691
768 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 128, 192, 256, 384, 768
634 : 1, 2, 317, 634
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 920,812,691,768,634, is 1.
Now, the common factors can be found like this.
920:2x 2x 2x 5x 23
812:2x 2x 7x 29
691:691
768:2x 2x 2x 2x 2x 2x 2x 2x 3
634:2x 317
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 2x 2 = 64
Therefore, the value for common factors is 64.
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 = 251346233671680/(1x64)
LCM = 251346233671680/64
LCM = 3927284901120
Thus, we can understand that the LCM of 920,812,691,768,634 is 3927284901120.
