Given numbers are 780,524,372,751,657
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 780,524,372,751,657 is 520968715020.
Find LCM of 780,524,372,751,657 with Prime Factorization
| 2 | 780, 524, 372, 751, 657 |
| 2 | 390, 262, 186, 751, 657 |
| 3 | 195, 131, 93, 751, 657 |
| 65, 131, 31, 751, 219 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 65 x 131 x 31 x 751 x 219 = 520968715020
Therefore, the lowest common multiple of 780,524,372,751,657 is 520968715020.
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.
780 x 524 x 372 x 751 x 657 = 75019494962880
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.
780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780
524 : 1, 2, 4, 131, 262, 524
372 : 1, 2, 3, 4, 6, 12, 31, 62, 93, 124, 186, 372
751 : 1, 751
657 : 1, 3, 9, 73, 219, 657
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 780,524,372,751,657, is 1.
Now, the common factors can be found like this.
780:2x 2x 3x 5x 13
524:2x 2x 131
372:2x 2x 3x 31
751:751
657:3x 3x 73
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 2x 3x 3 = 144
Therefore, the value for common factors is 144.
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 = 75019494962880/(1x144)
LCM = 75019494962880/144
LCM = 520968715020
Thus, we can understand that the LCM of 780,524,372,751,657 is 520968715020.
