Given numbers are 655,786,577,291
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 655,786,577,291 is 219958170.
Find LCM of 655,786,577,291 with Prime Factorization
| 3 | 655, 786, 577, 291 |
| 131 | 655, 262, 577, 97 |
| 5, 2, 577, 97 |
Multiply the prime numbers at the bottom and the left side.
3 x 131 x 5 x 2 x 577 x 97 = 219958170
Therefore, the lowest common multiple of 655,786,577,291 is 219958170.
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.
655 x 786 x 577 x 291 = 86443560810
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.
655 : 1, 5, 131, 655
786 : 1, 2, 3, 6, 131, 262, 393, 786
577 : 1, 577
291 : 1, 3, 97, 291
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 655,786,577,291, is 1.
Now, the common factors can be found like this.
655:5x 131
786:2x 3x 131
577:577
291:3x 97
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 131 = 393
Therefore, the value for common factors is 393.
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 = 86443560810/(1x393)
LCM = 86443560810/393
LCM = 219958170
Thus, we can understand that the LCM of 655,786,577,291 is 219958170.
