Given numbers are 178,760,676,438,637
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 178,760,676,438,637 is 122667777960.
Find LCM of 178,760,676,438,637 with Prime Factorization
| 2 | 178, 760, 676, 438, 637 |
| 2 | 89, 380, 338, 219, 637 |
| 13 | 89, 190, 169, 219, 637 |
| 89, 190, 13, 219, 49 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 13 x 89 x 190 x 13 x 219 x 49 = 122667777960
Therefore, the lowest common multiple of 178,760,676,438,637 is 122667777960.
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.
178 x 760 x 676 x 438 x 637 = 25514897815680
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.
178 : 1, 2, 89, 178
760 : 1, 2, 4, 5, 8, 10, 19, 20, 38, 40, 76, 95, 152, 190, 380, 760
676 : 1, 2, 4, 13, 26, 52, 169, 338, 676
438 : 1, 2, 3, 6, 73, 146, 219, 438
637 : 1, 7, 13, 49, 91, 637
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 178,760,676,438,637, is 1.
Now, the common factors can be found like this.
178:2x 89
760:2x 2x 2x 5x 19
676:2x 2x 13x 13
438:2x 3x 73
637:7x 7x 13
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 2x 2x 13 = 208
Therefore, the value for common factors is 208.
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 = 25514897815680/(1x208)
LCM = 25514897815680/208
LCM = 122667777960
Thus, we can understand that the LCM of 178,760,676,438,637 is 122667777960.
