Given numbers are 639,813,338,884,222
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 639,813,338,884,222 is 73632151476.
Find LCM of 639,813,338,884,222 with Prime Factorization
| 2 | 639, 813, 338, 884, 222 |
| 3 | 639, 813, 169, 442, 111 |
| 13 | 213, 271, 169, 442, 37 |
| 213, 271, 13, 34, 37 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 13 x 213 x 271 x 13 x 34 x 37 = 73632151476
Therefore, the lowest common multiple of 639,813,338,884,222 is 73632151476.
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.
639 x 813 x 338 x 884 x 222 = 34459846890768
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.
639 : 1, 3, 9, 71, 213, 639
813 : 1, 3, 271, 813
338 : 1, 2, 13, 26, 169, 338
884 : 1, 2, 4, 13, 17, 26, 34, 52, 68, 221, 442, 884
222 : 1, 2, 3, 6, 37, 74, 111, 222
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 639,813,338,884,222, is 1.
Now, the common factors can be found like this.
639:3x 3x 71
813:3x 271
338:2x 13x 13
884:2x 2x 13x 17
222:2x 3x 37
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 3x 3x 13 = 468
Therefore, the value for common factors is 468.
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 = 34459846890768/(1x468)
LCM = 34459846890768/468
LCM = 73632151476
Thus, we can understand that the LCM of 639,813,338,884,222 is 73632151476.
