Find LCM of 430,921,748,645,709 with Prime Factorization
| 2 | 430, 921, 748, 645, 709 |
| 3 | 215, 921, 374, 645, 709 |
| 5 | 215, 307, 374, 215, 709 |
| 43 | 43, 307, 374, 43, 709 |
| 1, 307, 374, 1, 709 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 43 x 1 x 307 x 374 x 1 x 709 = 105013690980
Therefore, the lowest common multiple of 430,921,748,645,709 is 105013690980.
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.
430 x 921 x 748 x 645 x 709 = 135467661364200
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.
430 : 1, 2, 5, 10, 43, 86, 215, 430
921 : 1, 3, 307, 921
748 : 1, 2, 4, 11, 17, 22, 34, 44, 68, 187, 374, 748
645 : 1, 3, 5, 15, 43, 129, 215, 645
709 : 1, 709
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 430,921,748,645,709, is 1.
Now, the common factors can be found like this.
430:2x 5x 43
921:3x 307
748:2x 2x 11x 17
645:3x 5x 43
709:709
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 5x 43 = 1290
Therefore, the value for common factors is 1290.
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 = 135467661364200/(1x1290)
LCM = 135467661364200/1290
LCM = 105013690980
Thus, we can understand that the LCM of 430,921,748,645,709 is 105013690980.
