The LCM of 757,470,899,638,870 is 10555221930.
Find LCM of 757,470,899,638,870 with Prime Factorization
| 2 | 757, 470, 899, 638, 870 |
| 5 | 757, 235, 899, 319, 435 |
| 29 | 757, 47, 899, 319, 87 |
| 757, 47, 31, 11, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 29 x 757 x 47 x 31 x 11 x 3 = 10555221930
Therefore, the lowest common multiple of 757,470,899,638,870 is 10555221930.
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.
757 x 470 x 899 x 638 x 870 = 177538832862600
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.
757 : 1, 757
470 : 1, 2, 5, 10, 47, 94, 235, 470
899 : 1, 29, 31, 899
638 : 1, 2, 11, 22, 29, 58, 319, 638
870 : 1, 2, 3, 5, 6, 10, 15, 29, 30, 58, 87, 145, 174, 290, 435, 870
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 757,470,899,638,870, is 1.
Now, the common factors can be found like this.
757:757
470:2x 5x 47
899:29x 31
638:2x 11x 29
870:2x 3x 5x 29
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 5x 29x 29 = 16820
Therefore, the value for common factors is 16820.
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 = 177538832862600/(1x16820)
LCM = 177538832862600/16820
LCM = 10555221930
Thus, we can understand that the LCM of 757,470,899,638,870 is 10555221930.
