Find LCM of 785,528,613,744,660 with Prime Factorization
| 2 | 785, 528, 613, 744, 660 |
| 2 | 785, 264, 613, 372, 330 |
| 2 | 785, 132, 613, 186, 165 |
| 3 | 785, 66, 613, 93, 165 |
| 5 | 785, 22, 613, 31, 55 |
| 11 | 157, 22, 613, 31, 11 |
| 157, 2, 613, 31, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 5 x 11 x 157 x 2 x 613 x 31 x 1 = 7876363440
Therefore, the lowest common multiple of 785,528,613,744,660 is 7876363440.
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.
785 x 528 x 613 x 744 x 660 = 124761596889600
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.
785 : 1, 5, 157, 785
528 : 1, 2, 3, 4, 6, 8, 11, 12, 16, 22, 24, 33, 44, 48, 66, 88, 132, 176, 264, 528
613 : 1, 613
744 : 1, 2, 3, 4, 6, 8, 12, 24, 31, 62, 93, 124, 186, 248, 372, 744
660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 785,528,613,744,660, is 1.
Now, the common factors can be found like this.
785:5x 157
528:2x 2x 2x 2x 3x 11
613:613
744:2x 2x 2x 3x 31
660:2x 2x 3x 5x 11
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 3x 3x 5x 11 = 15840
Therefore, the value for common factors is 15840.
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 = 124761596889600/(1x15840)
LCM = 124761596889600/15840
LCM = 7876363440
Thus, we can understand that the LCM of 785,528,613,744,660 is 7876363440.
