Find LCM of 680,615,637,922,120 with Prime Factorization
2 | 680, 615, 637, 922, 120 |
2 | 340, 615, 637, 461, 60 |
2 | 170, 615, 637, 461, 30 |
3 | 85, 615, 637, 461, 15 |
5 | 85, 205, 637, 461, 5 |
17, 41, 637, 461, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 5 x 17 x 41 x 637 x 461 x 1 = 24561471480
Therefore, the lowest common multiple of 680,615,637,922,120 is 24561471480.
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.
680 x 615 x 637 x 922 x 120 = 29473765776000
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.
680 : 1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, 680
615 : 1, 3, 5, 15, 41, 123, 205, 615
637 : 1, 7, 13, 49, 91, 637
922 : 1, 2, 461, 922
120 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, 120
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 680,615,637,922,120, is 1.
Now, the common factors can be found like this.
680:2x 2x 2x 5x 17
615:3x 5x 41
637:7x 7x 13
922:2x 461
120:2x 2x 2x 3x 5
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 3x 5x 5 = 1200
Therefore, the value for common factors is 1200.
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 = 29473765776000/(1x1200)
LCM = 29473765776000/1200
LCM = 24561471480
Thus, we can understand that the LCM of 680,615,637,922,120 is 24561471480.
