Given numbers are 639,556,169,376
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 639,556,169,376 is 5644041624.
Find LCM of 639,556,169,376 with Prime Factorization
2 | 639, 556, 169, 376 |
2 | 639, 278, 169, 188 |
639, 139, 169, 94 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 639 x 139 x 169 x 94 = 5644041624
Therefore, the lowest common multiple of 639,556,169,376 is 5644041624.
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 556 x 169 x 376 = 22576166496
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
556 : 1, 2, 4, 139, 278, 556
169 : 1, 13, 169
376 : 1, 2, 4, 8, 47, 94, 188, 376
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 639,556,169,376, is 1.
Now, the common factors can be found like this.
639:3x 3x 71
556:2x 2x 139
169:13x 13
376:2x 2x 2x 47
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 = 22576166496/(1x4)
LCM = 22576166496/4
LCM = 5644041624
Thus, we can understand that the LCM of 639,556,169,376 is 5644041624.
