Find LCM of 772,871,640,341,220 with Prime Factorization
2 | 772, 871, 640, 341, 220 |
2 | 386, 871, 320, 341, 110 |
5 | 193, 871, 160, 341, 55 |
11 | 193, 871, 32, 341, 11 |
193, 871, 32, 31, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 11 x 193 x 871 x 32 x 31 x 1 = 36686798720
Therefore, the lowest common multiple of 772,871,640,341,220 is 36686798720.
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.
772 x 871 x 640 x 341 x 220 = 32284382873600
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.
772 : 1, 2, 4, 193, 386, 772
871 : 1, 13, 67, 871
640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640
341 : 1, 11, 31, 341
220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 772,871,640,341,220, is 1.
Now, the common factors can be found like this.
772:2x 2x 193
871:13x 67
640:2x 2x 2x 2x 2x 2x 2x 5
341:11x 31
220:2x 2x 5x 11
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 5x 11 = 880
Therefore, the value for common factors is 880.
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 = 32284382873600/(1x880)
LCM = 32284382873600/880
LCM = 36686798720
Thus, we can understand that the LCM of 772,871,640,341,220 is 36686798720.
