The LCM of 211,656,220,720 is 68515920.
Find LCM of 211,656,220,720 with Prime Factorization
2 | 211, 656, 220, 720 |
2 | 211, 328, 110, 360 |
2 | 211, 164, 55, 180 |
2 | 211, 82, 55, 90 |
5 | 211, 41, 55, 45 |
211, 41, 11, 9 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 5 x 211 x 41 x 11 x 9 = 68515920
Therefore, the lowest common multiple of 211,656,220,720 is 68515920.
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.
211 x 656 x 220 x 720 = 21925094400
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.
211 : 1, 211
656 : 1, 2, 4, 8, 16, 41, 82, 164, 328, 656
220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220
720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 211,656,220,720, is 1.
Now, the common factors can be found like this.
211:211
656:2x 2x 2x 2x 41
220:2x 2x 5x 11
720:2x 2x 2x 2x 3x 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 2x 2x 5 = 320
Therefore, the value for common factors is 320.
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 = 21925094400/(1x320)
LCM = 21925094400/320
LCM = 68515920
Thus, we can understand that the LCM of 211,656,220,720 is 68515920.
