Given numbers are 669,793,385,638,124
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 669,793,385,638,124 is 734479565820.
Find LCM of 669,793,385,638,124 with Prime Factorization
2 | 669, 793, 385, 638, 124 |
11 | 669, 793, 385, 319, 62 |
669, 793, 35, 29, 62 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 669 x 793 x 35 x 29 x 62 = 734479565820
Therefore, the lowest common multiple of 669,793,385,638,124 is 734479565820.
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.
669 x 793 x 385 x 638 x 124 = 16158550448040
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.
669 : 1, 3, 223, 669
793 : 1, 13, 61, 793
385 : 1, 5, 7, 11, 35, 55, 77, 385
638 : 1, 2, 11, 22, 29, 58, 319, 638
124 : 1, 2, 4, 31, 62, 124
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 669,793,385,638,124, is 1.
Now, the common factors can be found like this.
669:3x 223
793:13x 61
385:5x 7x 11
638:2x 11x 29
124:2x 2x 31
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 11 = 22
Therefore, the value for common factors is 22.
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 = 16158550448040/(1x22)
LCM = 16158550448040/22
LCM = 734479565820
Thus, we can understand that the LCM of 669,793,385,638,124 is 734479565820.
