The LCM of 372,681,966,189 is 122359356.
Find LCM of 372,681,966,189 with Prime Factorization
| 2 | 372, 681, 966, 189 |
| 3 | 186, 681, 483, 189 |
| 7 | 62, 227, 161, 63 |
| 62, 227, 23, 9 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 62 x 227 x 23 x 9 = 122359356
Therefore, the lowest common multiple of 372,681,966,189 is 122359356.
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.
372 x 681 x 966 x 189 = 46251836568
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.
372 : 1, 2, 3, 4, 6, 12, 31, 62, 93, 124, 186, 372
681 : 1, 3, 227, 681
966 : 1, 2, 3, 6, 7, 14, 21, 23, 42, 46, 69, 138, 161, 322, 483, 966
189 : 1, 3, 7, 9, 21, 27, 63, 189
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 372,681,966,189, is 3.
Now, the common factors can be found like this.
372:2x 2x 3x 31
681:3x 227
966:2x 3x 7x 23
189:3x 3x 3x 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 3x 3x 7 = 126
Therefore, the value for common factors is 126.
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 = 46251836568/(3x126)
LCM = 46251836568/378
LCM = 122359356
Thus, we can understand that the LCM of 372,681,966,189 is 122359356.
