The LCM of 722,912,520,520 is 1126320.
Find LCM of 722,912,520,520 with Prime Factorization
| 2 | 722, 912, 520, 520 |
| 2 | 361, 456, 260, 260 |
| 2 | 361, 228, 130, 130 |
| 5 | 361, 114, 65, 65 |
| 13 | 361, 114, 13, 13 |
| 19 | 361, 114, 1, 1 |
| 19, 6, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 5 x 13 x 19 x 19 x 6 x 1 x 1 = 1126320
Therefore, the lowest common multiple of 722,912,520,520 is 1126320.
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.
722 x 912 x 520 x 520 = 178048665600
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.
722 : 1, 2, 19, 38, 361, 722
912 : 1, 2, 3, 4, 6, 8, 12, 16, 19, 24, 38, 48, 57, 76, 114, 152, 228, 304, 456, 912
520 : 1, 2, 4, 5, 8, 10, 13, 20, 26, 40, 52, 65, 104, 130, 260, 520
520 : 1, 2, 4, 5, 8, 10, 13, 20, 26, 40, 52, 65, 104, 130, 260, 520
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 722,912,520,520, is 2.
Now, the common factors can be found like this.
722:2x 19x 19
912:2x 2x 2x 2x 3x 19
520:2x 2x 2x 5x 13
520:2x 2x 2x 5x 13
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 2x 5x 13x 19 = 79040
Therefore, the value for common factors is 79040.
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 = 178048665600/(2x79040)
LCM = 178048665600/158080
LCM = 1126320
Thus, we can understand that the LCM of 722,912,520,520 is 1126320.
