Given numbers are 639,159,400,869,476
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 639,159,400,869,476 is 1400888134800.
Find LCM of 639,159,400,869,476 with Prime Factorization
| 2 | 639, 159, 400, 869, 476 |
| 2 | 639, 159, 200, 869, 238 |
| 3 | 639, 159, 100, 869, 119 |
| 213, 53, 100, 869, 119 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 213 x 53 x 100 x 869 x 119 = 1400888134800
Therefore, the lowest common multiple of 639,159,400,869,476 is 1400888134800.
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 159 x 400 x 869 x 476 = 16810657617600
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
159 : 1, 3, 53, 159
400 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 40, 50, 80, 100, 200, 400
869 : 1, 11, 79, 869
476 : 1, 2, 4, 7, 14, 17, 28, 34, 68, 119, 238, 476
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 639,159,400,869,476, is 1.
Now, the common factors can be found like this.
639:3x 3x 71
159:3x 53
400:2x 2x 2x 2x 5x 5
869:11x 79
476:2x 2x 7x 17
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 3 = 12
Therefore, the value for common factors is 12.
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 = 16810657617600/(1x12)
LCM = 16810657617600/12
LCM = 1400888134800
Thus, we can understand that the LCM of 639,159,400,869,476 is 1400888134800.
