Given numbers are 583,742,256,641
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 583,742,256,641 is 669675776.
Find LCM of 583,742,256,641 with Prime Factorization
| 2 | 583, 742, 256, 641 |
| 53 | 583, 371, 128, 641 |
| 11, 7, 128, 641 |
Multiply the prime numbers at the bottom and the left side.
2 x 53 x 11 x 7 x 128 x 641 = 669675776
Therefore, the lowest common multiple of 583,742,256,641 is 669675776.
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.
583 x 742 x 256 x 641 = 70985632256
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.
583 : 1, 11, 53, 583
742 : 1, 2, 7, 14, 53, 106, 371, 742
256 : 1, 2, 4, 8, 16, 32, 64, 128, 256
641 : 1, 641
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 583,742,256,641, is 1.
Now, the common factors can be found like this.
583:11x 53
742:2x 7x 53
256:2x 2x 2x 2x 2x 2x 2x 2
641:641
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 53 = 106
Therefore, the value for common factors is 106.
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 = 70985632256/(1x106)
LCM = 70985632256/106
LCM = 669675776
Thus, we can understand that the LCM of 583,742,256,641 is 669675776.
