Find LCM of 527,644,994,420,640 with Prime Factorization
| 2 | 527, 644, 994, 420, 640 |
| 2 | 527, 322, 497, 210, 320 |
| 5 | 527, 161, 497, 105, 160 |
| 7 | 527, 161, 497, 21, 32 |
| 527, 23, 71, 3, 32 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 7 x 527 x 23 x 71 x 3 x 32 = 11566343040
Therefore, the lowest common multiple of 527,644,994,420,640 is 11566343040.
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.
527 x 644 x 994 x 420 x 640 = 90680129433600
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.
527 : 1, 17, 31, 527
644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644
994 : 1, 2, 7, 14, 71, 142, 497, 994
420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420
640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 527,644,994,420,640, is 1.
Now, the common factors can be found like this.
527:17x 31
644:2x 2x 7x 23
994:2x 7x 71
420:2x 2x 3x 5x 7
640:2x 2x 2x 2x 2x 2x 2x 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 5x 7x 7 = 7840
Therefore, the value for common factors is 7840.
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 = 90680129433600/(1x7840)
LCM = 90680129433600/7840
LCM = 11566343040
Thus, we can understand that the LCM of 527,644,994,420,640 is 11566343040.
