The LCM of 561,634,136,267 is 126619944.
Find LCM of 561,634,136,267 with Prime Factorization
| 2 | 561, 634, 136, 267 |
| 3 | 561, 317, 68, 267 |
| 17 | 187, 317, 68, 89 |
| 11, 317, 4, 89 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 17 x 11 x 317 x 4 x 89 = 126619944
Therefore, the lowest common multiple of 561,634,136,267 is 126619944.
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 634 x 136 x 267 = 12915234288
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
634 : 1, 2, 317, 634
136 : 1, 2, 4, 8, 17, 34, 68, 136
267 : 1, 3, 89, 267
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 561,634,136,267, is 1.
Now, the common factors can be found like this.
561:3x 11x 17
634:2x 317
136:2x 2x 2x 17
267:3x 89
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 17 = 102
Therefore, the value for common factors is 102.
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 = 12915234288/(1x102)
LCM = 12915234288/102
LCM = 126619944
Thus, we can understand that the LCM of 561,634,136,267 is 126619944.
