Given numbers are 748,730,172,989,454
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 748,730,172,989,454 is 61293809060.
Find LCM of 748,730,172,989,454 with Prime Factorization
| 2 | 748, 730, 172, 989, 454 |
| 2 | 374, 365, 86, 989, 227 |
| 43 | 187, 365, 43, 989, 227 |
| 187, 365, 1, 23, 227 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 43 x 187 x 365 x 1 x 23 x 227 = 61293809060
Therefore, the lowest common multiple of 748,730,172,989,454 is 61293809060.
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.
748 x 730 x 172 x 989 x 454 = 42170140633280
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.
748 : 1, 2, 4, 11, 17, 22, 34, 44, 68, 187, 374, 748
730 : 1, 2, 5, 10, 73, 146, 365, 730
172 : 1, 2, 4, 43, 86, 172
989 : 1, 23, 43, 989
454 : 1, 2, 227, 454
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 748,730,172,989,454, is 1.
Now, the common factors can be found like this.
748:2x 2x 11x 17
730:2x 5x 73
172:2x 2x 43
989:23x 43
454:2x 227
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 43 = 688
Therefore, the value for common factors is 688.
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 = 42170140633280/(1x688)
LCM = 42170140633280/688
LCM = 61293809060
Thus, we can understand that the LCM of 748,730,172,989,454 is 61293809060.
