Given numbers are 653,442,171,711,634
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 653,442,171,711,634 is 1235998416978.
Find LCM of 653,442,171,711,634 with Prime Factorization
| 2 | 653, 442, 171, 711, 634 |
| 3 | 653, 221, 171, 711, 317 |
| 3 | 653, 221, 57, 237, 317 |
| 653, 221, 19, 79, 317 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 653 x 221 x 19 x 79 x 317 = 1235998416978
Therefore, the lowest common multiple of 653,442,171,711,634 is 1235998416978.
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.
653 x 442 x 171 x 711 x 634 = 22247971505604
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.
653 : 1, 653
442 : 1, 2, 13, 17, 26, 34, 221, 442
171 : 1, 3, 9, 19, 57, 171
711 : 1, 3, 9, 79, 237, 711
634 : 1, 2, 317, 634
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 653,442,171,711,634, is 1.
Now, the common factors can be found like this.
653:653
442:2x 13x 17
171:3x 3x 19
711:3x 3x 79
634:2x 317
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 3 = 18
Therefore, the value for common factors is 18.
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 = 22247971505604/(1x18)
LCM = 22247971505604/18
LCM = 1235998416978
Thus, we can understand that the LCM of 653,442,171,711,634 is 1235998416978.
