Given numbers are 724,611,572,321
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 724,611,572,321 is 1561987284.
Find LCM of 724,611,572,321 with Prime Factorization
| 2 | 724, 611, 572, 321 |
| 2 | 362, 611, 286, 321 |
| 13 | 181, 611, 143, 321 |
| 181, 47, 11, 321 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 13 x 181 x 47 x 11 x 321 = 1561987284
Therefore, the lowest common multiple of 724,611,572,321 is 1561987284.
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.
724 x 611 x 572 x 321 = 81223338768
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.
724 : 1, 2, 4, 181, 362, 724
611 : 1, 13, 47, 611
572 : 1, 2, 4, 11, 13, 22, 26, 44, 52, 143, 286, 572
321 : 1, 3, 107, 321
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 724,611,572,321, is 1.
Now, the common factors can be found like this.
724:2x 2x 181
611:13x 47
572:2x 2x 11x 13
321:3x 107
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 13 = 52
Therefore, the value for common factors is 52.
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 = 81223338768/(1x52)
LCM = 81223338768/52
LCM = 1561987284
Thus, we can understand that the LCM of 724,611,572,321 is 1561987284.
