Given numbers are 470,747,681,688,828
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 470,747,681,688,828 is 630566066160.
Find LCM of 470,747,681,688,828 with Prime Factorization
| 2 | 470, 747, 681, 688, 828 |
| 2 | 235, 747, 681, 344, 414 |
| 3 | 235, 747, 681, 172, 207 |
| 3 | 235, 249, 227, 172, 69 |
| 235, 83, 227, 172, 23 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 235 x 83 x 227 x 172 x 23 = 630566066160
Therefore, the lowest common multiple of 470,747,681,688,828 is 630566066160.
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.
470 x 747 x 681 x 688 x 828 = 136202270290560
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.
470 : 1, 2, 5, 10, 47, 94, 235, 470
747 : 1, 3, 9, 83, 249, 747
681 : 1, 3, 227, 681
688 : 1, 2, 4, 8, 16, 43, 86, 172, 344, 688
828 : 1, 2, 3, 4, 6, 9, 12, 18, 23, 36, 46, 69, 92, 138, 207, 276, 414, 828
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 470,747,681,688,828, is 1.
Now, the common factors can be found like this.
470:2x 5x 47
747:3x 3x 83
681:3x 227
688:2x 2x 2x 2x 43
828:2x 2x 3x 3x 23
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 3x 3x 3 = 216
Therefore, the value for common factors is 216.
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 = 136202270290560/(1x216)
LCM = 136202270290560/216
LCM = 630566066160
Thus, we can understand that the LCM of 470,747,681,688,828 is 630566066160.
