Find LCM of 561,681,807,688,476 with Prime Factorization
| 2 | 561, 681, 807, 688, 476 |
| 2 | 561, 681, 807, 344, 238 |
| 3 | 561, 681, 807, 172, 119 |
| 17 | 187, 227, 269, 172, 119 |
| 11, 227, 269, 172, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 17 x 11 x 227 x 269 x 172 x 7 = 164978547888
Therefore, the lowest common multiple of 561,681,807,688,476 is 164978547888.
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 681 x 807 x 688 x 476 = 100966871307456
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
681 : 1, 3, 227, 681
807 : 1, 3, 269, 807
688 : 1, 2, 4, 8, 16, 43, 86, 172, 344, 688
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 561,681,807,688,476, is 1.
Now, the common factors can be found like this.
561:3x 11x 17
681:3x 227
807:3x 269
688:2x 2x 2x 2x 43
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 3x 3x 17 = 612
Therefore, the value for common factors is 612.
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 = 100966871307456/(1x612)
LCM = 100966871307456/612
LCM = 164978547888
Thus, we can understand that the LCM of 561,681,807,688,476 is 164978547888.
