Given numbers are 379,780,379,472
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 379,780,379,472 is 34883160.
Find LCM of 379,780,379,472 with Prime Factorization
| 2 | 379, 780, 379, 472 |
| 2 | 379, 390, 379, 236 |
| 379 | 379, 195, 379, 118 |
| 1, 195, 1, 118 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 379 x 1 x 195 x 1 x 118 = 34883160
Therefore, the lowest common multiple of 379,780,379,472 is 34883160.
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.
379 x 780 x 379 x 472 = 52882870560
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.
379 : 1, 379
780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780
379 : 1, 379
472 : 1, 2, 4, 8, 59, 118, 236, 472
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 379,780,379,472, is 1.
Now, the common factors can be found like this.
379:379
780:2x 2x 3x 5x 13
379:379
472:2x 2x 2x 59
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 379 = 1516
Therefore, the value for common factors is 1516.
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 = 52882870560/(1x1516)
LCM = 52882870560/1516
LCM = 34883160
Thus, we can understand that the LCM of 379,780,379,472 is 34883160.
