Given numbers are 657,545,780,698,525
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 657,545,780,698,525 is 227435726700.
Find LCM of 657,545,780,698,525 with Prime Factorization
| 2 | 657, 545, 780, 698, 525 |
| 3 | 657, 545, 390, 349, 525 |
| 5 | 219, 545, 130, 349, 175 |
| 219, 109, 26, 349, 35 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 219 x 109 x 26 x 349 x 35 = 227435726700
Therefore, the lowest common multiple of 657,545,780,698,525 is 227435726700.
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.
657 x 545 x 780 x 698 x 525 = 102346077015000
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.
657 : 1, 3, 9, 73, 219, 657
545 : 1, 5, 109, 545
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
698 : 1, 2, 349, 698
525 : 1, 3, 5, 7, 15, 21, 25, 35, 75, 105, 175, 525
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 657,545,780,698,525, is 1.
Now, the common factors can be found like this.
657:3x 3x 73
545:5x 109
780:2x 2x 3x 5x 13
698:2x 349
525:3x 5x 5x 7
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 5x 5 = 450
Therefore, the value for common factors is 450.
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 = 102346077015000/(1x450)
LCM = 102346077015000/450
LCM = 227435726700
Thus, we can understand that the LCM of 657,545,780,698,525 is 227435726700.
