Given numbers are 620,651,707,744
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 620,651,707,744 is 2630040.
Find LCM of 620,651,707,744 with Prime Factorization
| 2 | 620, 651, 707, 744 |
| 2 | 310, 651, 707, 372 |
| 3 | 155, 651, 707, 186 |
| 7 | 155, 217, 707, 62 |
| 31 | 155, 31, 101, 62 |
| 5, 1, 101, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 31 x 5 x 1 x 101 x 2 = 2630040
Therefore, the lowest common multiple of 620,651,707,744 is 2630040.
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 651 x 707 x 744 = 212307348960
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
651 : 1, 3, 7, 21, 31, 93, 217, 651
707 : 1, 7, 101, 707
744 : 1, 2, 3, 4, 6, 8, 12, 24, 31, 62, 93, 124, 186, 248, 372, 744
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 620,651,707,744, is 1.
Now, the common factors can be found like this.
620:2x 2x 5x 31
651:3x 7x 31
707:7x 101
744:2x 2x 2x 3x 31
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 3x 7x 31x 31 = 80724
Therefore, the value for common factors is 80724.
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 = 212307348960/(1x80724)
LCM = 212307348960/80724
LCM = 2630040
Thus, we can understand that the LCM of 620,651,707,744 is 2630040.
