The LCM of 919,572,216,643 is 18252244296.
Find LCM of 919,572,216,643 with Prime Factorization
| 2 | 919, 572, 216, 643 |
| 2 | 919, 286, 108, 643 |
| 919, 143, 54, 643 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 919 x 143 x 54 x 643 = 18252244296
Therefore, the lowest common multiple of 919,572,216,643 is 18252244296.
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.
919 x 572 x 216 x 643 = 73008977184
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.
919 : 1, 919
572 : 1, 2, 4, 11, 13, 22, 26, 44, 52, 143, 286, 572
216 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 108, 216
643 : 1, 643
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 919,572,216,643, is 1.
Now, the common factors can be found like this.
919:919
572:2x 2x 11x 13
216:2x 2x 2x 3x 3x 3
643:643
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2 = 4
Therefore, the value for common factors is 4.
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 = 73008977184/(1x4)
LCM = 73008977184/4
LCM = 18252244296
Thus, we can understand that the LCM of 919,572,216,643 is 18252244296.
