Given numbers are 620,552,598,621
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 620,552,598,621 is 10010520.
Find LCM of 620,552,598,621 with Prime Factorization
| 2 | 620, 552, 598, 621 |
| 2 | 310, 276, 299, 621 |
| 3 | 155, 138, 299, 621 |
| 23 | 155, 46, 299, 207 |
| 155, 2, 13, 9 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 23 x 155 x 2 x 13 x 9 = 10010520
Therefore, the lowest common multiple of 620,552,598,621 is 10010520.
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.
620 x 552 x 598 x 621 = 127093561920
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.
620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620
552 : 1, 2, 3, 4, 6, 8, 12, 23, 24, 46, 69, 92, 138, 184, 276, 552
598 : 1, 2, 13, 23, 26, 46, 299, 598
621 : 1, 3, 9, 23, 27, 69, 207, 621
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 620,552,598,621, is 1.
Now, the common factors can be found like this.
620:2x 2x 5x 31
552:2x 2x 2x 3x 23
598:2x 13x 23
621:3x 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 23x 23 = 12696
Therefore, the value for common factors is 12696.
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 = 127093561920/(1x12696)
LCM = 127093561920/12696
LCM = 10010520
Thus, we can understand that the LCM of 620,552,598,621 is 10010520.
