Find LCM of 712,646,234,520,862 with Prime Factorization
| 2 | 712, 646, 234, 520, 862 |
| 2 | 356, 323, 117, 260, 431 |
| 2 | 178, 323, 117, 130, 431 |
| 13 | 89, 323, 117, 65, 431 |
| 89, 323, 9, 5, 431 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 13 x 89 x 323 x 9 x 5 x 431 = 57984998760
Therefore, the lowest common multiple of 712,646,234,520,862 is 57984998760.
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.
712 x 646 x 234 x 520 x 862 = 48243518968320
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.
712 : 1, 2, 4, 8, 89, 178, 356, 712
646 : 1, 2, 17, 19, 34, 38, 323, 646
234 : 1, 2, 3, 6, 9, 13, 18, 26, 39, 78, 117, 234
520 : 1, 2, 4, 5, 8, 10, 13, 20, 26, 40, 52, 65, 104, 130, 260, 520
862 : 1, 2, 431, 862
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 712,646,234,520,862, is 2.
Now, the common factors can be found like this.
712:2x 2x 2x 89
646:2x 17x 19
234:2x 3x 3x 13
520:2x 2x 2x 5x 13
862:2x 431
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 13 = 416
Therefore, the value for common factors is 416.
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 = 48243518968320/(2x416)
LCM = 48243518968320/832
LCM = 57984998760
Thus, we can understand that the LCM of 712,646,234,520,862 is 57984998760.
