Given numbers are 784,613,956,451
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 784,613,956,451 is 51802531088.
Find LCM of 784,613,956,451 with Prime Factorization
| 2 | 784, 613, 956, 451 |
| 2 | 392, 613, 478, 451 |
| 196, 613, 239, 451 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 196 x 613 x 239 x 451 = 51802531088
Therefore, the lowest common multiple of 784,613,956,451 is 51802531088.
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.
784 x 613 x 956 x 451 = 207210124352
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.
784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784
613 : 1, 613
956 : 1, 2, 4, 239, 478, 956
451 : 1, 11, 41, 451
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 784,613,956,451, is 1.
Now, the common factors can be found like this.
784:2x 2x 2x 2x 7x 7
613:613
956:2x 2x 239
451:11x 41
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2 = 4
Therefore, the value for common factors is 4.
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 = 207210124352/(1x4)
LCM = 207210124352/4
LCM = 51802531088
Thus, we can understand that the LCM of 784,613,956,451 is 51802531088.
