Find LCM of 637,124,869,286,992 with Prime Factorization
| 2 | 637, 124, 869, 286, 992 |
| 2 | 637, 62, 869, 143, 496 |
| 11 | 637, 31, 869, 143, 248 |
| 13 | 637, 31, 79, 13, 248 |
| 31 | 49, 31, 79, 1, 248 |
| 49, 1, 79, 1, 8 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 11 x 13 x 31 x 49 x 1 x 79 x 1 x 8 = 549124576
Therefore, the lowest common multiple of 637,124,869,286,992 is 549124576.
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 124 x 869 x 286 x 992 = 19474153963264
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
124 : 1, 2, 4, 31, 62, 124
869 : 1, 11, 79, 869
286 : 1, 2, 11, 13, 22, 26, 143, 286
992 : 1, 2, 4, 8, 16, 31, 32, 62, 124, 248, 496, 992
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 637,124,869,286,992, is 1.
Now, the common factors can be found like this.
637:7x 7x 13
124:2x 2x 31
869:11x 79
286:2x 11x 13
992:2x 2x 2x 2x 2x 31
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 11x 13x 31 = 35464
Therefore, the value for common factors is 35464.
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 = 19474153963264/(1x35464)
LCM = 19474153963264/35464
LCM = 549124576
Thus, we can understand that the LCM of 637,124,869,286,992 is 549124576.
