Given numbers are 521,782,748,611,904
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 521,782,748,611,904 is 1237704034424.
Find LCM of 521,782,748,611,904 with Prime Factorization
| 2 | 521, 782, 748, 611, 904 |
| 2 | 521, 391, 374, 611, 452 |
| 17 | 521, 391, 187, 611, 226 |
| 521, 23, 11, 611, 226 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 17 x 521 x 23 x 11 x 611 x 226 = 1237704034424
Therefore, the lowest common multiple of 521,782,748,611,904 is 1237704034424.
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.
521 x 782 x 748 x 611 x 904 = 168327748681664
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.
521 : 1, 521
782 : 1, 2, 17, 23, 34, 46, 391, 782
748 : 1, 2, 4, 11, 17, 22, 34, 44, 68, 187, 374, 748
611 : 1, 13, 47, 611
904 : 1, 2, 4, 8, 113, 226, 452, 904
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 521,782,748,611,904, is 1.
Now, the common factors can be found like this.
521:521
782:2x 17x 23
748:2x 2x 11x 17
611:13x 47
904:2x 2x 2x 113
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 17 = 136
Therefore, the value for common factors is 136.
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 = 168327748681664/(1x136)
LCM = 168327748681664/136
LCM = 1237704034424
Thus, we can understand that the LCM of 521,782,748,611,904 is 1237704034424.
