Find LCM of 637,384,861,138,152 with Prime Factorization
2 | 637, 384, 861, 138, 152 |
2 | 637, 192, 861, 69, 76 |
2 | 637, 96, 861, 69, 38 |
3 | 637, 48, 861, 69, 19 |
7 | 637, 16, 287, 23, 19 |
91, 16, 41, 23, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 7 x 91 x 16 x 41 x 23 x 19 = 4382641536
Therefore, the lowest common multiple of 637,384,861,138,152 is 4382641536.
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 384 x 861 x 138 x 152 = 4417702668288
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
384 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 128, 192, 384
861 : 1, 3, 7, 21, 41, 123, 287, 861
138 : 1, 2, 3, 6, 23, 46, 69, 138
152 : 1, 2, 4, 8, 19, 38, 76, 152
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 637,384,861,138,152, is 1.
Now, the common factors can be found like this.
637:7x 7x 13
384:2x 2x 2x 2x 2x 2x 2x 3
861:3x 7x 41
138:2x 3x 23
152:2x 2x 2x 19
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 3x 3x 7 = 1008
Therefore, the value for common factors is 1008.
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 = 4417702668288/(1x1008)
LCM = 4417702668288/1008
LCM = 4382641536
Thus, we can understand that the LCM of 637,384,861,138,152 is 4382641536.
