Given numbers are 639,483,952,842,769
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 639,483,952,842,769 is 4529748378456.
Find LCM of 639,483,952,842,769 with Prime Factorization
| 2 | 639, 483, 952, 842, 769 |
| 3 | 639, 483, 476, 421, 769 |
| 7 | 213, 161, 476, 421, 769 |
| 213, 23, 68, 421, 769 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 213 x 23 x 68 x 421 x 769 = 4529748378456
Therefore, the lowest common multiple of 639,483,952,842,769 is 4529748378456.
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 483 x 952 x 842 x 769 = 190249431895152
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
483 : 1, 3, 7, 21, 23, 69, 161, 483
952 : 1, 2, 4, 7, 8, 14, 17, 28, 34, 56, 68, 119, 136, 238, 476, 952
842 : 1, 2, 421, 842
769 : 1, 769
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 639,483,952,842,769, is 1.
Now, the common factors can be found like this.
639:3x 3x 71
483:3x 7x 23
952:2x 2x 2x 7x 17
842:2x 421
769:769
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 7 = 42
Therefore, the value for common factors is 42.
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 = 190249431895152/(1x42)
LCM = 190249431895152/42
LCM = 4529748378456
Thus, we can understand that the LCM of 639,483,952,842,769 is 4529748378456.
