The LCM of 649,472,557,156 is 112785816.
Find LCM of 649,472,557,156 with Prime Factorization
| 2 | 649, 472, 557, 156 |
| 2 | 649, 236, 557, 78 |
| 59 | 649, 118, 557, 39 |
| 11, 2, 557, 39 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 59 x 11 x 2 x 557 x 39 = 112785816
Therefore, the lowest common multiple of 649,472,557,156 is 112785816.
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.
649 x 472 x 557 x 156 = 26617452576
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.
649 : 1, 11, 59, 649
472 : 1, 2, 4, 8, 59, 118, 236, 472
557 : 1, 557
156 : 1, 2, 3, 4, 6, 12, 13, 26, 39, 52, 78, 156
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 649,472,557,156, is 1.
Now, the common factors can be found like this.
649:11x 59
472:2x 2x 2x 59
557:557
156:2x 2x 3x 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 59 = 236
Therefore, the value for common factors is 236.
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 = 26617452576/(1x236)
LCM = 26617452576/236
LCM = 112785816
Thus, we can understand that the LCM of 649,472,557,156 is 112785816.
