Find LCM of 947,492,744,287,128 with Prime Factorization
| 2 | 947, 492, 744, 287, 128 |
| 2 | 947, 246, 372, 287, 64 |
| 2 | 947, 123, 186, 287, 32 |
| 3 | 947, 123, 93, 287, 16 |
| 41 | 947, 41, 31, 287, 16 |
| 947, 1, 31, 7, 16 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 41 x 947 x 1 x 31 x 7 x 16 = 3235376256
Therefore, the lowest common multiple of 947,492,744,287,128 is 3235376256.
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.
947 x 492 x 744 x 287 x 128 = 12734440943616
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.
947 : 1, 947
492 : 1, 2, 3, 4, 6, 12, 41, 82, 123, 164, 246, 492
744 : 1, 2, 3, 4, 6, 8, 12, 24, 31, 62, 93, 124, 186, 248, 372, 744
287 : 1, 7, 41, 287
128 : 1, 2, 4, 8, 16, 32, 64, 128
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 947,492,744,287,128, is 1.
Now, the common factors can be found like this.
947:947
492:2x 2x 3x 41
744:2x 2x 2x 3x 31
287:7x 41
128:2x 2x 2x 2x 2x 2x 2
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 41 = 3936
Therefore, the value for common factors is 3936.
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 = 12734440943616/(1x3936)
LCM = 12734440943616/3936
LCM = 3235376256
Thus, we can understand that the LCM of 947,492,744,287,128 is 3235376256.
