Given numbers are 762,700,642,331,784
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 762,700,642,331,784 is 264479989200.
Find LCM of 762,700,642,331,784 with Prime Factorization
| 2 | 762, 700, 642, 331, 784 |
| 2 | 381, 350, 321, 331, 392 |
| 3 | 381, 175, 321, 331, 196 |
| 7 | 127, 175, 107, 331, 196 |
| 127, 25, 107, 331, 28 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 127 x 25 x 107 x 331 x 28 = 264479989200
Therefore, the lowest common multiple of 762,700,642,331,784 is 264479989200.
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.
762 x 700 x 642 x 331 x 784 = 88865276371200
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.
762 : 1, 2, 3, 6, 127, 254, 381, 762
700 : 1, 2, 4, 5, 7, 10, 14, 20, 25, 28, 35, 50, 70, 100, 140, 175, 350, 700
642 : 1, 2, 3, 6, 107, 214, 321, 642
331 : 1, 331
784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 762,700,642,331,784, is 1.
Now, the common factors can be found like this.
762:2x 3x 127
700:2x 2x 5x 5x 7
642:2x 3x 107
331:331
784:2x 2x 2x 2x 7x 7
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 7 = 336
Therefore, the value for common factors is 336.
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 = 88865276371200/(1x336)
LCM = 88865276371200/336
LCM = 264479989200
Thus, we can understand that the LCM of 762,700,642,331,784 is 264479989200.
