Given numbers are 639,957,316,316
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 639,957,316,316 is 64413756.
Find LCM of 639,957,316,316 with Prime Factorization
| 2 | 639, 957, 316, 316 |
| 2 | 639, 957, 158, 158 |
| 3 | 639, 957, 79, 79 |
| 79 | 213, 319, 79, 79 |
| 213, 319, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 79 x 213 x 319 x 1 x 1 = 64413756
Therefore, the lowest common multiple of 639,957,316,316 is 64413756.
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 957 x 316 x 316 = 61064240688
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
957 : 1, 3, 11, 29, 33, 87, 319, 957
316 : 1, 2, 4, 79, 158, 316
316 : 1, 2, 4, 79, 158, 316
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 639,957,316,316, is 1.
Now, the common factors can be found like this.
639:3x 3x 71
957:3x 11x 29
316:2x 2x 79
316:2x 2x 79
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 79 = 948
Therefore, the value for common factors is 948.
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 = 61064240688/(1x948)
LCM = 61064240688/948
LCM = 64413756
Thus, we can understand that the LCM of 639,957,316,316 is 64413756.
