Find LCM of 291,665,532,418,178 with Prime Factorization
| 2 | 291, 665, 532, 418, 178 |
| 7 | 291, 665, 266, 209, 89 |
| 19 | 291, 95, 38, 209, 89 |
| 291, 5, 2, 11, 89 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 19 x 291 x 5 x 2 x 11 x 89 = 757804740
Therefore, the lowest common multiple of 291,665,532,418,178 is 757804740.
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.
291 x 665 x 532 x 418 x 178 = 7659890311920
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.
291 : 1, 3, 97, 291
665 : 1, 5, 7, 19, 35, 95, 133, 665
532 : 1, 2, 4, 7, 14, 19, 28, 38, 76, 133, 266, 532
418 : 1, 2, 11, 19, 22, 38, 209, 418
178 : 1, 2, 89, 178
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 291,665,532,418,178, is 1.
Now, the common factors can be found like this.
291:3x 97
665:5x 7x 19
532:2x 2x 7x 19
418:2x 11x 19
178:2x 89
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 7x 19x 19 = 10108
Therefore, the value for common factors is 10108.
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 = 7659890311920/(1x10108)
LCM = 7659890311920/10108
LCM = 757804740
Thus, we can understand that the LCM of 291,665,532,418,178 is 757804740.
