Given numbers are 124,765,854,651
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 124,765,854,651 is 40505220.
Find LCM of 124,765,854,651 with Prime Factorization
| 2 | 124, 765, 854, 651 |
| 3 | 62, 765, 427, 651 |
| 7 | 62, 255, 427, 217 |
| 31 | 62, 255, 61, 31 |
| 2, 255, 61, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 31 x 2 x 255 x 61 x 1 = 40505220
Therefore, the lowest common multiple of 124,765,854,651 is 40505220.
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.
124 x 765 x 854 x 651 = 52737796440
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.
124 : 1, 2, 4, 31, 62, 124
765 : 1, 3, 5, 9, 15, 17, 45, 51, 85, 153, 255, 765
854 : 1, 2, 7, 14, 61, 122, 427, 854
651 : 1, 3, 7, 21, 31, 93, 217, 651
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 124,765,854,651, is 1.
Now, the common factors can be found like this.
124:2x 2x 31
765:3x 3x 5x 17
854:2x 7x 61
651:3x 7x 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 3x 7x 31 = 1302
Therefore, the value for common factors is 1302.
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 = 52737796440/(1x1302)
LCM = 52737796440/1302
LCM = 40505220
Thus, we can understand that the LCM of 124,765,854,651 is 40505220.
