Given numbers are 744,391,426,874,715
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 744,391,426,874,715 is 280587089640.
Find LCM of 744,391,426,874,715 with Prime Factorization
| 2 | 744, 391, 426, 874, 715 |
| 3 | 372, 391, 213, 437, 715 |
| 23 | 124, 391, 71, 437, 715 |
| 124, 17, 71, 19, 715 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 23 x 124 x 17 x 71 x 19 x 715 = 280587089640
Therefore, the lowest common multiple of 744,391,426,874,715 is 280587089640.
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.
744 x 391 x 426 x 874 x 715 = 77442036740640
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.
744 : 1, 2, 3, 4, 6, 8, 12, 24, 31, 62, 93, 124, 186, 248, 372, 744
391 : 1, 17, 23, 391
426 : 1, 2, 3, 6, 71, 142, 213, 426
874 : 1, 2, 19, 23, 38, 46, 437, 874
715 : 1, 5, 11, 13, 55, 65, 143, 715
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 744,391,426,874,715, is 1.
Now, the common factors can be found like this.
744:2x 2x 2x 3x 31
391:17x 23
426:2x 3x 71
874:2x 19x 23
715:5x 11x 13
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 = 77442036740640/(1x276)
LCM = 77442036740640/276
LCM = 280587089640
Thus, we can understand that the LCM of 744,391,426,874,715 is 280587089640.
