Given numbers are 748,418,902,147
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 748,418,902,147 is 85655724.
Find LCM of 748,418,902,147 with Prime Factorization
| 2 | 748, 418, 902, 147 |
| 11 | 374, 209, 451, 147 |
| 34, 19, 41, 147 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 34 x 19 x 41 x 147 = 85655724
Therefore, the lowest common multiple of 748,418,902,147 is 85655724.
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 418 x 902 x 147 = 41457370416
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
418 : 1, 2, 11, 19, 22, 38, 209, 418
902 : 1, 2, 11, 22, 41, 82, 451, 902
147 : 1, 3, 7, 21, 49, 147
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 748,418,902,147, is 1.
Now, the common factors can be found like this.
748:2x 2x 11x 17
418:2x 11x 19
902:2x 11x 41
147:3x 7x 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 11x 11 = 484
Therefore, the value for common factors is 484.
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 = 41457370416/(1x484)
LCM = 41457370416/484
LCM = 85655724
Thus, we can understand that the LCM of 748,418,902,147 is 85655724.
