Given numbers are 392,646,187,894
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 392,646,187,894 is 622570872.
Find LCM of 392,646,187,894 with Prime Factorization
2 | 392, 646, 187, 894 |
17 | 196, 323, 187, 447 |
196, 19, 11, 447 |
Multiply the prime numbers at the bottom and the left side.
2 x 17 x 196 x 19 x 11 x 447 = 622570872
Therefore, the lowest common multiple of 392,646,187,894 is 622570872.
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.
392 x 646 x 187 x 894 = 42334819296
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.
392 : 1, 2, 4, 7, 8, 14, 28, 49, 56, 98, 196, 392
646 : 1, 2, 17, 19, 34, 38, 323, 646
187 : 1, 11, 17, 187
894 : 1, 2, 3, 6, 149, 298, 447, 894
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 392,646,187,894, is 1.
Now, the common factors can be found like this.
392:2x 2x 2x 7x 7
646:2x 17x 19
187:11x 17
894:2x 3x 149
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 17 = 68
Therefore, the value for common factors is 68.
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 = 42334819296/(1x68)
LCM = 42334819296/68
LCM = 622570872
Thus, we can understand that the LCM of 392,646,187,894 is 622570872.
