Given numbers are 510,619,764,720
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 510,619,764,720 is 1447122960.
Find LCM of 510,619,764,720 with Prime Factorization
| 2 | 510, 619, 764, 720 |
| 2 | 255, 619, 382, 360 |
| 3 | 255, 619, 191, 180 |
| 5 | 85, 619, 191, 60 |
| 17, 619, 191, 12 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 17 x 619 x 191 x 12 = 1447122960
Therefore, the lowest common multiple of 510,619,764,720 is 1447122960.
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.
510 x 619 x 764 x 720 = 173654755200
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.
510 : 1, 2, 3, 5, 6, 10, 15, 17, 30, 34, 51, 85, 102, 170, 255, 510
619 : 1, 619
764 : 1, 2, 4, 191, 382, 764
720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 510,619,764,720, is 1.
Now, the common factors can be found like this.
510:2x 3x 5x 17
619:619
764:2x 2x 191
720:2x 2x 2x 2x 3x 3x 5
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 5 = 120
Therefore, the value for common factors is 120.
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 = 173654755200/(1x120)
LCM = 173654755200/120
LCM = 1447122960
Thus, we can understand that the LCM of 510,619,764,720 is 1447122960.
