The LCM of 436,759,350,780,989 is 32372640300.
Find LCM of 436,759,350,780,989 with Prime Factorization
| 2 | 436, 759, 350, 780, 989 |
| 2 | 218, 759, 175, 390, 989 |
| 3 | 109, 759, 175, 195, 989 |
| 5 | 109, 253, 175, 65, 989 |
| 23 | 109, 253, 35, 13, 989 |
| 109, 11, 35, 13, 43 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 23 x 109 x 11 x 35 x 13 x 43 = 32372640300
Therefore, the lowest common multiple of 436,759,350,780,989 is 32372640300.
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.
436 x 759 x 350 x 780 x 989 = 89348487228000
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.
436 : 1, 2, 4, 109, 218, 436
759 : 1, 3, 11, 23, 33, 69, 253, 759
350 : 1, 2, 5, 7, 10, 14, 25, 35, 50, 70, 175, 350
780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780
989 : 1, 23, 43, 989
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 436,759,350,780,989, is 1.
Now, the common factors can be found like this.
436:2x 2x 109
759:3x 11x 23
350:2x 5x 5x 7
780:2x 2x 3x 5x 13
989:23x 43
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 3x 5x 23 = 2760
Therefore, the value for common factors is 2760.
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 = 89348487228000/(1x2760)
LCM = 89348487228000/2760
LCM = 32372640300
Thus, we can understand that the LCM of 436,759,350,780,989 is 32372640300.
