Find LCM of 976,172,984,321,421 with Prime Factorization
| 2 | 976, 172, 984, 321, 421 |
| 2 | 488, 86, 492, 321, 421 |
| 2 | 244, 43, 246, 321, 421 |
| 3 | 122, 43, 123, 321, 421 |
| 122, 43, 41, 107, 421 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 122 x 43 x 41 x 107 x 421 = 232535497008
Therefore, the lowest common multiple of 976,172,984,321,421 is 232535497008.
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.
976 x 172 x 984 x 321 x 421 = 22323407712768
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.
976 : 1, 2, 4, 8, 16, 61, 122, 244, 488, 976
172 : 1, 2, 4, 43, 86, 172
984 : 1, 2, 3, 4, 6, 8, 12, 24, 41, 82, 123, 164, 246, 328, 492, 984
321 : 1, 3, 107, 321
421 : 1, 421
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 976,172,984,321,421, is 1.
Now, the common factors can be found like this.
976:2x 2x 2x 2x 61
172:2x 2x 43
984:2x 2x 2x 3x 41
321:3x 107
421:421
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 2x 2x 3 = 96
Therefore, the value for common factors is 96.
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 = 22323407712768/(1x96)
LCM = 22323407712768/96
LCM = 232535497008
Thus, we can understand that the LCM of 976,172,984,321,421 is 232535497008.
