Given numbers are 602,638,822,763,643
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 602,638,822,763,643 is 5531799962766.
Find LCM of 602,638,822,763,643 with Prime Factorization
| 2 | 602, 638, 822, 763, 643 |
| 7 | 301, 319, 411, 763, 643 |
| 43, 319, 411, 109, 643 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 43 x 319 x 411 x 109 x 643 = 5531799962766
Therefore, the lowest common multiple of 602,638,822,763,643 is 5531799962766.
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.
602 x 638 x 822 x 763 x 643 = 154890398957448
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.
602 : 1, 2, 7, 14, 43, 86, 301, 602
638 : 1, 2, 11, 22, 29, 58, 319, 638
822 : 1, 2, 3, 6, 137, 274, 411, 822
763 : 1, 7, 109, 763
643 : 1, 643
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 602,638,822,763,643, is 1.
Now, the common factors can be found like this.
602:2x 7x 43
638:2x 11x 29
822:2x 3x 137
763:7x 109
643:643
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 7 = 28
Therefore, the value for common factors is 28.
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 = 154890398957448/(1x28)
LCM = 154890398957448/28
LCM = 5531799962766
Thus, we can understand that the LCM of 602,638,822,763,643 is 5531799962766.
