Given numbers are 791,611,846,572
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 791,611,846,572 is 191387196.
Find LCM of 791,611,846,572 with Prime Factorization
| 2 | 791, 611, 846, 572 |
| 13 | 791, 611, 423, 286 |
| 47 | 791, 47, 423, 22 |
| 791, 1, 9, 22 |
Multiply the prime numbers at the bottom and the left side.
2 x 13 x 47 x 791 x 1 x 9 x 22 = 191387196
Therefore, the lowest common multiple of 791,611,846,572 is 191387196.
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.
791 x 611 x 846 x 572 = 233875153512
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.
791 : 1, 7, 113, 791
611 : 1, 13, 47, 611
846 : 1, 2, 3, 6, 9, 18, 47, 94, 141, 282, 423, 846
572 : 1, 2, 4, 11, 13, 22, 26, 44, 52, 143, 286, 572
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 791,611,846,572, is 1.
Now, the common factors can be found like this.
791:7x 113
611:13x 47
846:2x 3x 3x 47
572:2x 2x 11x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 13x 47 = 1222
Therefore, the value for common factors is 1222.
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 = 233875153512/(1x1222)
LCM = 233875153512/1222
LCM = 191387196
Thus, we can understand that the LCM of 791,611,846,572 is 191387196.
