The LCM of 639,856,207,437,523 is 125013740184.
Find LCM of 639,856,207,437,523 with Prime Factorization
| 3 | 639, 856, 207, 437, 523 |
| 3 | 213, 856, 69, 437, 523 |
| 23 | 71, 856, 23, 437, 523 |
| 71, 856, 1, 19, 523 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 23 x 71 x 856 x 1 x 19 x 523 = 125013740184
Therefore, the lowest common multiple of 639,856,207,437,523 is 125013740184.
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 856 x 207 x 437 x 523 = 25877844218088
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
856 : 1, 2, 4, 8, 107, 214, 428, 856
207 : 1, 3, 9, 23, 69, 207
437 : 1, 19, 23, 437
523 : 1, 523
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 639,856,207,437,523, is 1.
Now, the common factors can be found like this.
639:3x 3x 71
856:2x 2x 2x 107
207:3x 3x 23
437:19x 23
523:523
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 23 = 207
Therefore, the value for common factors is 207.
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 = 25877844218088/(1x207)
LCM = 25877844218088/207
LCM = 125013740184
Thus, we can understand that the LCM of 639,856,207,437,523 is 125013740184.
