Given numbers are 715,564,400,992
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 715,564,400,992 is 500042400.
Find LCM of 715,564,400,992 with Prime Factorization
| 2 | 715, 564, 400, 992 |
| 2 | 715, 282, 200, 496 |
| 2 | 715, 141, 100, 248 |
| 2 | 715, 141, 50, 124 |
| 5 | 715, 141, 25, 62 |
| 143, 141, 5, 62 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 5 x 143 x 141 x 5 x 62 = 500042400
Therefore, the lowest common multiple of 715,564,400,992 is 500042400.
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.
715 x 564 x 400 x 992 = 160013568000
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.
715 : 1, 5, 11, 13, 55, 65, 143, 715
564 : 1, 2, 3, 4, 6, 12, 47, 94, 141, 188, 282, 564
400 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 40, 50, 80, 100, 200, 400
992 : 1, 2, 4, 8, 16, 31, 32, 62, 124, 248, 496, 992
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 715,564,400,992, is 1.
Now, the common factors can be found like this.
715:5x 11x 13
564:2x 2x 3x 47
400:2x 2x 2x 2x 5x 5
992:2x 2x 2x 2x 2x 31
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 2x 5 = 320
Therefore, the value for common factors is 320.
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 = 160013568000/(1x320)
LCM = 160013568000/320
LCM = 500042400
Thus, we can understand that the LCM of 715,564,400,992 is 500042400.
