Given numbers are 437,490,931,640
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 437,490,931,640 is 13704320.
Find LCM of 437,490,931,640 with Prime Factorization
| 2 | 437, 490, 931, 640 |
| 5 | 437, 245, 931, 320 |
| 7 | 437, 49, 931, 64 |
| 7 | 437, 7, 133, 64 |
| 19 | 437, 1, 19, 64 |
| 23, 1, 1, 64 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 7 x 7 x 19 x 23 x 1 x 1 x 64 = 13704320
Therefore, the lowest common multiple of 437,490,931,640 is 13704320.
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.
437 x 490 x 931 x 640 = 127587219200
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.
437 : 1, 19, 23, 437
490 : 1, 2, 5, 7, 10, 14, 35, 49, 70, 98, 245, 490
931 : 1, 7, 19, 49, 133, 931
640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 437,490,931,640, is 1.
Now, the common factors can be found like this.
437:19x 23
490:2x 5x 7x 7
931:7x 7x 19
640:2x 2x 2x 2x 2x 2x 2x 5
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 7x 7x 19 = 9310
Therefore, the value for common factors is 9310.
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 = 127587219200/(1x9310)
LCM = 127587219200/9310
LCM = 13704320
Thus, we can understand that the LCM of 437,490,931,640 is 13704320.
