Given numbers are 637,494,430,715,248
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 637,494,430,715,248 is 7098651560.
Find LCM of 637,494,430,715,248 with Prime Factorization
| 2 | 637, 494, 430, 715, 248 |
| 5 | 637, 247, 215, 715, 124 |
| 13 | 637, 247, 43, 143, 124 |
| 49, 19, 43, 11, 124 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 13 x 49 x 19 x 43 x 11 x 124 = 7098651560
Therefore, the lowest common multiple of 637,494,430,715,248 is 7098651560.
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.
637 x 494 x 430 x 715 x 248 = 23993442272800
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.
637 : 1, 7, 13, 49, 91, 637
494 : 1, 2, 13, 19, 26, 38, 247, 494
430 : 1, 2, 5, 10, 43, 86, 215, 430
715 : 1, 5, 11, 13, 55, 65, 143, 715
248 : 1, 2, 4, 8, 31, 62, 124, 248
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 637,494,430,715,248, is 1.
Now, the common factors can be found like this.
637:7x 7x 13
494:2x 13x 19
430:2x 5x 43
715:5x 11x 13
248:2x 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 5x 13x 13 = 3380
Therefore, the value for common factors is 3380.
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 = 23993442272800/(1x3380)
LCM = 23993442272800/3380
LCM = 7098651560
Thus, we can understand that the LCM of 637,494,430,715,248 is 7098651560.
