Given numbers are 657,137,219,919,987
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 657,137,219,919,987 is 27214311159.
Find LCM of 657,137,219,919,987 with Prime Factorization
| 3 | 657, 137, 219, 919, 987 |
| 73 | 219, 137, 73, 919, 329 |
| 3, 137, 1, 919, 329 |
Multiply the prime numbers at the bottom and the left side.
3 x 73 x 3 x 137 x 1 x 919 x 329 = 27214311159
Therefore, the lowest common multiple of 657,137,219,919,987 is 27214311159.
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.
657 x 137 x 219 x 919 x 987 = 17879802431463
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.
657 : 1, 3, 9, 73, 219, 657
137 : 1, 137
219 : 1, 3, 73, 219
919 : 1, 919
987 : 1, 3, 7, 21, 47, 141, 329, 987
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 657,137,219,919,987, is 1.
Now, the common factors can be found like this.
657:3x 3x 73
137:137
219:3x 73
919:919
987:3x 7x 47
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 73 = 657
Therefore, the value for common factors is 657.
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 = 17879802431463/(1x657)
LCM = 17879802431463/657
LCM = 27214311159
Thus, we can understand that the LCM of 657,137,219,919,987 is 27214311159.
