Find LCM of 644,437,893,254,582 with Prime Factorization
| 2 | 644, 437, 893, 254, 582 |
| 19 | 322, 437, 893, 127, 291 |
| 23 | 322, 23, 47, 127, 291 |
| 14, 1, 47, 127, 291 |
Multiply the prime numbers at the bottom and the left side.
2 x 19 x 23 x 14 x 1 x 47 x 127 x 291 = 21253675044
Therefore, the lowest common multiple of 644,437,893,254,582 is 21253675044.
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.
644 x 437 x 893 x 254 x 582 = 37151423976912
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.
644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644
437 : 1, 19, 23, 437
893 : 1, 19, 47, 893
254 : 1, 2, 127, 254
582 : 1, 2, 3, 6, 97, 194, 291, 582
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 644,437,893,254,582, is 1.
Now, the common factors can be found like this.
644:2x 2x 7x 23
437:19x 23
893:19x 47
254:2x 127
582:2x 3x 97
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 19x 23 = 1748
Therefore, the value for common factors is 1748.
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 = 37151423976912/(1x1748)
LCM = 37151423976912/1748
LCM = 21253675044
Thus, we can understand that the LCM of 644,437,893,254,582 is 21253675044.
