Given numbers are 657,281,766,452,978
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 657,281,766,452,978 is 5209505521236.
Find LCM of 657,281,766,452,978 with Prime Factorization
2 | 657, 281, 766, 452, 978 |
3 | 657, 281, 383, 226, 489 |
219, 281, 383, 226, 163 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 219 x 281 x 383 x 226 x 163 = 5209505521236
Therefore, the lowest common multiple of 657,281,766,452,978 is 5209505521236.
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 281 x 766 x 452 x 978 = 62514066254832
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
281 : 1, 281
766 : 1, 2, 383, 766
452 : 1, 2, 4, 113, 226, 452
978 : 1, 2, 3, 6, 163, 326, 489, 978
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 657,281,766,452,978, is 1.
Now, the common factors can be found like this.
657:3x 3x 73
281:281
766:2x 383
452:2x 2x 113
978:2x 3x 163
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 3 = 12
Therefore, the value for common factors is 12.
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 = 62514066254832/(1x12)
LCM = 62514066254832/12
LCM = 5209505521236
Thus, we can understand that the LCM of 657,281,766,452,978 is 5209505521236.
