Given numbers are 587,689,572,390
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 587,689,572,390 is 266932380.
Find LCM of 587,689,572,390 with Prime Factorization
| 2 | 587, 689, 572, 390 |
| 13 | 587, 689, 286, 195 |
| 587, 53, 22, 15 |
Multiply the prime numbers at the bottom and the left side.
2 x 13 x 587 x 53 x 22 x 15 = 266932380
Therefore, the lowest common multiple of 587,689,572,390 is 266932380.
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.
587 x 689 x 572 x 390 = 90223144440
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.
587 : 1, 587
689 : 1, 13, 53, 689
572 : 1, 2, 4, 11, 13, 22, 26, 44, 52, 143, 286, 572
390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 587,689,572,390, is 1.
Now, the common factors can be found like this.
587:587
689:13x 53
572:2x 2x 11x 13
390:2x 3x 5x 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 13x 13 = 338
Therefore, the value for common factors is 338.
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 = 90223144440/(1x338)
LCM = 90223144440/338
LCM = 266932380
Thus, we can understand that the LCM of 587,689,572,390 is 266932380.
