Given numbers are 671,839,812,456
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 671,839,812,456 is 52112914392.
Find LCM of 671,839,812,456 with Prime Factorization
| 2 | 671, 839, 812, 456 |
| 2 | 671, 839, 406, 228 |
| 671, 839, 203, 114 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 671 x 839 x 203 x 114 = 52112914392
Therefore, the lowest common multiple of 671,839,812,456 is 52112914392.
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.
671 x 839 x 812 x 456 = 208451657568
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.
671 : 1, 11, 61, 671
839 : 1, 839
812 : 1, 2, 4, 7, 14, 28, 29, 58, 116, 203, 406, 812
456 : 1, 2, 3, 4, 6, 8, 12, 19, 24, 38, 57, 76, 114, 152, 228, 456
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 671,839,812,456, is 1.
Now, the common factors can be found like this.
671:11x 61
839:839
812:2x 2x 7x 29
456:2x 2x 2x 3x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2 = 4
Therefore, the value for common factors is 4.
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 = 208451657568/(1x4)
LCM = 208451657568/4
LCM = 52112914392
Thus, we can understand that the LCM of 671,839,812,456 is 52112914392.
