The LCM of 639,732,334,707,639 is 18408846204.
Find LCM of 639,732,334,707,639 with Prime Factorization
| 2 | 639, 732, 334, 707, 639 |
| 3 | 639, 366, 167, 707, 639 |
| 3 | 213, 122, 167, 707, 213 |
| 71 | 71, 122, 167, 707, 71 |
| 1, 122, 167, 707, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 71 x 1 x 122 x 167 x 707 x 1 = 18408846204
Therefore, the lowest common multiple of 639,732,334,707,639 is 18408846204.
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 732 x 334 x 707 x 639 = 70579516346136
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
732 : 1, 2, 3, 4, 6, 12, 61, 122, 183, 244, 366, 732
334 : 1, 2, 167, 334
707 : 1, 7, 101, 707
639 : 1, 3, 9, 71, 213, 639
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 639,732,334,707,639, is 1.
Now, the common factors can be found like this.
639:3x 3x 71
732:2x 2x 3x 61
334:2x 167
707:7x 101
639:3x 3x 71
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 3x 71 = 3834
Therefore, the value for common factors is 3834.
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 = 70579516346136/(1x3834)
LCM = 70579516346136/3834
LCM = 18408846204
Thus, we can understand that the LCM of 639,732,334,707,639 is 18408846204.
