Given numbers are 462,651,549,735,643
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 462,651,549,735,643 is 58983939630.
Find LCM of 462,651,549,735,643 with Prime Factorization
| 3 | 462, 651, 549, 735, 643 |
| 7 | 154, 217, 183, 245, 643 |
| 22, 31, 183, 35, 643 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 22 x 31 x 183 x 35 x 643 = 58983939630
Therefore, the lowest common multiple of 462,651,549,735,643 is 58983939630.
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.
462 x 651 x 549 x 735 x 643 = 78035752130490
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.
462 : 1, 2, 3, 6, 7, 11, 14, 21, 22, 33, 42, 66, 77, 154, 231, 462
651 : 1, 3, 7, 21, 31, 93, 217, 651
549 : 1, 3, 9, 61, 183, 549
735 : 1, 3, 5, 7, 15, 21, 35, 49, 105, 147, 245, 735
643 : 1, 643
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 462,651,549,735,643, is 1.
Now, the common factors can be found like this.
462:2x 3x 7x 11
651:3x 7x 31
549:3x 3x 61
735:3x 5x 7x 7
643:643
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 3x 7x 7 = 1323
Therefore, the value for common factors is 1323.
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 = 78035752130490/(1x1323)
LCM = 78035752130490/1323
LCM = 58983939630
Thus, we can understand that the LCM of 462,651,549,735,643 is 58983939630.
