Given numbers are 637,786,718,681,120
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 637,786,718,681,120 is 816041564520.
Find LCM of 637,786,718,681,120 with Prime Factorization
2 | 637, 786, 718, 681, 120 |
3 | 637, 393, 359, 681, 60 |
637, 131, 359, 227, 20 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 637 x 131 x 359 x 227 x 20 = 816041564520
Therefore, the lowest common multiple of 637,786,718,681,120 is 816041564520.
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.
637 x 786 x 718 x 681 x 120 = 29377496322720
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.
637 : 1, 7, 13, 49, 91, 637
786 : 1, 2, 3, 6, 131, 262, 393, 786
718 : 1, 2, 359, 718
681 : 1, 3, 227, 681
120 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, 120
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 637,786,718,681,120, is 1.
Now, the common factors can be found like this.
637:7x 7x 13
786:2x 3x 131
718:2x 359
681:3x 227
120:2x 2x 2x 3x 5
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 3 = 36
Therefore, the value for common factors is 36.
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 = 29377496322720/(1x36)
LCM = 29377496322720/36
LCM = 816041564520
Thus, we can understand that the LCM of 637,786,718,681,120 is 816041564520.
