Given numbers are 657,228,865,448
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 657,228,865,448 is 4837412160.
Find LCM of 657,228,865,448 with Prime Factorization
2 | 657, 228, 865, 448 |
2 | 657, 114, 865, 224 |
3 | 657, 57, 865, 112 |
219, 19, 865, 112 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 219 x 19 x 865 x 112 = 4837412160
Therefore, the lowest common multiple of 657,228,865,448 is 4837412160.
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 228 x 865 x 448 = 58048945920
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
228 : 1, 2, 3, 4, 6, 12, 19, 38, 57, 76, 114, 228
865 : 1, 5, 173, 865
448 : 1, 2, 4, 7, 8, 14, 16, 28, 32, 56, 64, 112, 224, 448
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 657,228,865,448, is 1.
Now, the common factors can be found like this.
657:3x 3x 73
228:2x 2x 3x 19
865:5x 173
448:2x 2x 2x 2x 2x 2x 7
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 = 58048945920/(1x12)
LCM = 58048945920/12
LCM = 4837412160
Thus, we can understand that the LCM of 657,228,865,448 is 4837412160.
