Given numbers are 640,577,630,358
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 640,577,630,358 is 4164370560.
Find LCM of 640,577,630,358 with Prime Factorization
2 | 640, 577, 630, 358 |
5 | 320, 577, 315, 179 |
64, 577, 63, 179 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 64 x 577 x 63 x 179 = 4164370560
Therefore, the lowest common multiple of 640,577,630,358 is 4164370560.
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.
640 x 577 x 630 x 358 = 83287411200
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.
640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640
577 : 1, 577
630 : 1, 2, 3, 5, 6, 7, 9, 10, 14, 15, 18, 21, 30, 35, 42, 45, 63, 70, 90, 105, 126, 210, 315, 630
358 : 1, 2, 179, 358
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 640,577,630,358, is 1.
Now, the common factors can be found like this.
640:2x 2x 2x 2x 2x 2x 2x 5
577:577
630:2x 3x 3x 5x 7
358:2x 179
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 = 83287411200/(1x20)
LCM = 83287411200/20
LCM = 4164370560
Thus, we can understand that the LCM of 640,577,630,358 is 4164370560.
