Given numbers are 312,391,580,572
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 312,391,580,572 is 194577240.
Find LCM of 312,391,580,572 with Prime Factorization
2 | 312, 391, 580, 572 |
2 | 156, 391, 290, 286 |
13 | 78, 391, 145, 143 |
6, 391, 145, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 13 x 6 x 391 x 145 x 11 = 194577240
Therefore, the lowest common multiple of 312,391,580,572 is 194577240.
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.
312 x 391 x 580 x 572 = 40472065920
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.
312 : 1, 2, 3, 4, 6, 8, 12, 13, 24, 26, 39, 52, 78, 104, 156, 312
391 : 1, 17, 23, 391
580 : 1, 2, 4, 5, 10, 20, 29, 58, 116, 145, 290, 580
572 : 1, 2, 4, 11, 13, 22, 26, 44, 52, 143, 286, 572
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 312,391,580,572, is 1.
Now, the common factors can be found like this.
312:2x 2x 2x 3x 13
391:17x 23
580:2x 2x 5x 29
572:2x 2x 11x 13
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 13 = 208
Therefore, the value for common factors is 208.
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 = 40472065920/(1x208)
LCM = 40472065920/208
LCM = 194577240
Thus, we can understand that the LCM of 312,391,580,572 is 194577240.
