Find LCM of 637,428,868,840,894 with Prime Factorization
| 2 | 637, 428, 868, 840, 894 |
| 2 | 637, 214, 434, 420, 447 |
| 3 | 637, 107, 217, 210, 447 |
| 7 | 637, 107, 217, 70, 149 |
| 91, 107, 31, 10, 149 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 91 x 107 x 31 x 10 x 149 = 37779170520
Therefore, the lowest common multiple of 637,428,868,840,894 is 37779170520.
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.
637 x 428 x 868 x 840 x 894 = 177713218126080
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.
637 : 1, 7, 13, 49, 91, 637
428 : 1, 2, 4, 107, 214, 428
868 : 1, 2, 4, 7, 14, 28, 31, 62, 124, 217, 434, 868
840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840
894 : 1, 2, 3, 6, 149, 298, 447, 894
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 637,428,868,840,894, is 1.
Now, the common factors can be found like this.
637:7x 7x 13
428:2x 2x 107
868:2x 2x 7x 31
840:2x 2x 2x 3x 5x 7
894:2x 3x 149
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 2x 2x 2x 3x 7x 7 = 4704
Therefore, the value for common factors is 4704.
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 = 177713218126080/(1x4704)
LCM = 177713218126080/4704
LCM = 37779170520
Thus, we can understand that the LCM of 637,428,868,840,894 is 37779170520.
