Given numbers are 639,861,452,288
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 639,861,452,288 is 663149088.
Find LCM of 639,861,452,288 with Prime Factorization
2 | 639, 861, 452, 288 |
2 | 639, 861, 226, 144 |
3 | 639, 861, 113, 72 |
3 | 213, 287, 113, 24 |
71, 287, 113, 8 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 71 x 287 x 113 x 8 = 663149088
Therefore, the lowest common multiple of 639,861,452,288 is 663149088.
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.
639 x 861 x 452 x 288 = 71620101504
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.
639 : 1, 3, 9, 71, 213, 639
861 : 1, 3, 7, 21, 41, 123, 287, 861
452 : 1, 2, 4, 113, 226, 452
288 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 32, 36, 48, 72, 96, 144, 288
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 639,861,452,288, is 1.
Now, the common factors can be found like this.
639:3x 3x 71
861:3x 7x 41
452:2x 2x 113
288:2x 2x 2x 2x 2x 3x 3
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 3x 3 = 108
Therefore, the value for common factors is 108.
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 = 71620101504/(1x108)
LCM = 71620101504/108
LCM = 663149088
Thus, we can understand that the LCM of 639,861,452,288 is 663149088.
