Given numbers are 669,621,501,658,920
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 669,621,501,658,920 is 304346858760.
Find LCM of 669,621,501,658,920 with Prime Factorization
| 2 | 669, 621, 501, 658, 920 |
| 3 | 669, 621, 501, 329, 460 |
| 23 | 223, 207, 167, 329, 460 |
| 223, 9, 167, 329, 20 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 23 x 223 x 9 x 167 x 329 x 20 = 304346858760
Therefore, the lowest common multiple of 669,621,501,658,920 is 304346858760.
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.
669 x 621 x 501 x 658 x 920 = 125999599526640
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.
669 : 1, 3, 223, 669
621 : 1, 3, 9, 23, 27, 69, 207, 621
501 : 1, 3, 167, 501
658 : 1, 2, 7, 14, 47, 94, 329, 658
920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 669,621,501,658,920, is 1.
Now, the common factors can be found like this.
669:3x 223
621:3x 3x 3x 23
501:3x 167
658:2x 7x 47
920:2x 2x 2x 5x 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 3x 3x 23 = 414
Therefore, the value for common factors is 414.
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 = 125999599526640/(1x414)
LCM = 125999599526640/414
LCM = 304346858760
Thus, we can understand that the LCM of 669,621,501,658,920 is 304346858760.
