Find LCM of 748,665,535,238 with Prime Factorization
| 2 | 748, 665, 535, 238 |
| 5 | 374, 665, 535, 119 |
| 7 | 374, 133, 107, 119 |
| 17 | 374, 19, 107, 17 |
| 22, 19, 107, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 7 x 17 x 22 x 19 x 107 x 1 = 53223940
Therefore, the lowest common multiple of 748,665,535,238 is 53223940.
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 665 x 535 x 238 = 63336488600
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
665 : 1, 5, 7, 19, 35, 95, 133, 665
535 : 1, 5, 107, 535
238 : 1, 2, 7, 14, 17, 34, 119, 238
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 748,665,535,238, is 1.
Now, the common factors can be found like this.
748:2x 2x 11x 17
665:5x 7x 19
535:5x 107
238:2x 7x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 7x 17 = 1190
Therefore, the value for common factors is 1190.
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 = 63336488600/(1x1190)
LCM = 63336488600/1190
LCM = 53223940
Thus, we can understand that the LCM of 748,665,535,238 is 53223940.
