Given numbers are 493,370,638,992
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 493,370,638,992 is 995228960.
Find LCM of 493,370,638,992 with Prime Factorization
| 2 | 493, 370, 638, 992 |
| 29 | 493, 185, 319, 496 |
| 17, 185, 11, 496 |
Multiply the prime numbers at the bottom and the left side.
2 x 29 x 17 x 185 x 11 x 496 = 995228960
Therefore, the lowest common multiple of 493,370,638,992 is 995228960.
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.
493 x 370 x 638 x 992 = 115446559360
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.
493 : 1, 17, 29, 493
370 : 1, 2, 5, 10, 37, 74, 185, 370
638 : 1, 2, 11, 22, 29, 58, 319, 638
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 493,370,638,992, is 1.
Now, the common factors can be found like this.
493:17x 29
370:2x 5x 37
638:2x 11x 29
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 29 = 116
Therefore, the value for common factors is 116.
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 = 115446559360/(1x116)
LCM = 115446559360/116
LCM = 995228960
Thus, we can understand that the LCM of 493,370,638,992 is 995228960.
