Given numbers are 871,902,549,656,140
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 871,902,549,656,140 is 120768888240.
Find LCM of 871,902,549,656,140 with Prime Factorization
| 2 | 871, 902, 549, 656, 140 |
| 2 | 871, 451, 549, 328, 70 |
| 41 | 871, 451, 549, 164, 35 |
| 871, 11, 549, 4, 35 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 41 x 871 x 11 x 549 x 4 x 35 = 120768888240
Therefore, the lowest common multiple of 871,902,549,656,140 is 120768888240.
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.
871 x 902 x 549 x 656 x 140 = 39612195342720
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.
871 : 1, 13, 67, 871
902 : 1, 2, 11, 22, 41, 82, 451, 902
549 : 1, 3, 9, 61, 183, 549
656 : 1, 2, 4, 8, 16, 41, 82, 164, 328, 656
140 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 70, 140
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 871,902,549,656,140, is 1.
Now, the common factors can be found like this.
871:13x 67
902:2x 11x 41
549:3x 3x 61
656:2x 2x 2x 2x 41
140:2x 2x 5x 7
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 2x 41 = 328
Therefore, the value for common factors is 328.
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 = 39612195342720/(1x328)
LCM = 39612195342720/328
LCM = 120768888240
Thus, we can understand that the LCM of 871,902,549,656,140 is 120768888240.
