Find LCM of 640,724,765,808,965 with Prime Factorization
2 | 640, 724, 765, 808, 965 |
2 | 320, 362, 765, 404, 965 |
2 | 160, 181, 765, 202, 965 |
5 | 80, 181, 765, 101, 965 |
16, 181, 153, 101, 193 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 5 x 16 x 181 x 153 x 101 x 193 = 345484575360
Therefore, the lowest common multiple of 640,724,765,808,965 is 345484575360.
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 724 x 765 x 808 x 965 = 276387660288000
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
724 : 1, 2, 4, 181, 362, 724
765 : 1, 3, 5, 9, 15, 17, 45, 51, 85, 153, 255, 765
808 : 1, 2, 4, 8, 101, 202, 404, 808
965 : 1, 5, 193, 965
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 640,724,765,808,965, is 1.
Now, the common factors can be found like this.
640:2x 2x 2x 2x 2x 2x 2x 5
724:2x 2x 181
765:3x 3x 5x 17
808:2x 2x 2x 101
965:5x 193
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 2x 5x 5 = 800
Therefore, the value for common factors is 800.
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 = 276387660288000/(1x800)
LCM = 276387660288000/800
LCM = 345484575360
Thus, we can understand that the LCM of 640,724,765,808,965 is 345484575360.
