Given numbers are 643,736,475,965,492
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 643,736,475,965,492 is 5336356279200.
Find LCM of 643,736,475,965,492 with Prime Factorization
| 2 | 643, 736, 475, 965, 492 |
| 2 | 643, 368, 475, 965, 246 |
| 5 | 643, 184, 475, 965, 123 |
| 643, 184, 95, 193, 123 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 643 x 184 x 95 x 193 x 123 = 5336356279200
Therefore, the lowest common multiple of 643,736,475,965,492 is 5336356279200.
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.
643 x 736 x 475 x 965 x 492 = 106727125584000
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.
643 : 1, 643
736 : 1, 2, 4, 8, 16, 23, 32, 46, 92, 184, 368, 736
475 : 1, 5, 19, 25, 95, 475
965 : 1, 5, 193, 965
492 : 1, 2, 3, 4, 6, 12, 41, 82, 123, 164, 246, 492
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 643,736,475,965,492, is 1.
Now, the common factors can be found like this.
643:643
736:2x 2x 2x 2x 2x 23
475:5x 5x 19
965:5x 193
492:2x 2x 3x 41
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 5 = 20
Therefore, the value for common factors is 20.
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 = 106727125584000/(1x20)
LCM = 106727125584000/20
LCM = 5336356279200
Thus, we can understand that the LCM of 643,736,475,965,492 is 5336356279200.
