The LCM of 787,636,759,920 is 1266345960.
Find LCM of 787,636,759,920 with Prime Factorization
2 | 787, 636, 759, 920 |
2 | 787, 318, 759, 460 |
3 | 787, 159, 759, 230 |
23 | 787, 53, 253, 230 |
787, 53, 11, 10 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 23 x 787 x 53 x 11 x 10 = 1266345960
Therefore, the lowest common multiple of 787,636,759,920 is 1266345960.
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.
787 x 636 x 759 x 920 = 349511484960
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.
787 : 1, 787
636 : 1, 2, 3, 4, 6, 12, 53, 106, 159, 212, 318, 636
759 : 1, 3, 11, 23, 33, 69, 253, 759
920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 787,636,759,920, is 1.
Now, the common factors can be found like this.
787:787
636:2x 2x 3x 53
759:3x 11x 23
920:2x 2x 2x 5x 23
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 3x 23 = 276
Therefore, the value for common factors is 276.
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 = 349511484960/(1x276)
LCM = 349511484960/276
LCM = 1266345960
Thus, we can understand that the LCM of 787,636,759,920 is 1266345960.
