Find LCM of 561,973,572,840,476 with Prime Factorization
| 2 | 561, 973, 572, 840, 476 |
| 2 | 561, 973, 286, 420, 238 |
| 3 | 561, 973, 143, 210, 119 |
| 7 | 187, 973, 143, 70, 119 |
| 11 | 187, 139, 143, 10, 17 |
| 17 | 17, 139, 13, 10, 17 |
| 1, 139, 13, 10, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 11 x 17 x 1 x 139 x 13 x 10 x 1 = 283843560
Therefore, the lowest common multiple of 561,973,572,840,476 is 283843560.
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.
561 x 973 x 572 x 840 x 476 = 124841209933440
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.
561 : 1, 3, 11, 17, 33, 51, 187, 561
973 : 1, 7, 139, 973
572 : 1, 2, 4, 11, 13, 22, 26, 44, 52, 143, 286, 572
840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840
476 : 1, 2, 4, 7, 14, 17, 28, 34, 68, 119, 238, 476
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 561,973,572,840,476, is 1.
Now, the common factors can be found like this.
561:3x 11x 17
973:7x 139
572:2x 2x 11x 13
840:2x 2x 2x 3x 5x 7
476:2x 2x 7x 17
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 7x 7x 11x 17 = 439824
Therefore, the value for common factors is 439824.
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 = 124841209933440/(1x439824)
LCM = 124841209933440/439824
LCM = 283843560
Thus, we can understand that the LCM of 561,973,572,840,476 is 283843560.
