Find LCM of 391,988,577,420,565 with Prime Factorization
2 | 391, 988, 577, 420, 565 |
2 | 391, 494, 577, 210, 565 |
5 | 391, 247, 577, 105, 565 |
391, 247, 577, 21, 113 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 391 x 247 x 577 x 21 x 113 = 2644705130340
Therefore, the lowest common multiple of 391,988,577,420,565 is 2644705130340.
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.
391 x 988 x 577 x 420 x 565 = 52894102606800
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.
391 : 1, 17, 23, 391
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
577 : 1, 577
420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420
565 : 1, 5, 113, 565
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 391,988,577,420,565, is 1.
Now, the common factors can be found like this.
391:17x 23
988:2x 2x 13x 19
577:577
420:2x 2x 3x 5x 7
565:5x 113
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 5 = 20
Therefore, the value for common factors is 20.
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 = 52894102606800/(1x20)
LCM = 52894102606800/20
LCM = 2644705130340
Thus, we can understand that the LCM of 391,988,577,420,565 is 2644705130340.
