Given numbers are 636,681,764,188
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 636,681,764,188 is 1296027444.
Find LCM of 636,681,764,188 with Prime Factorization
| 2 | 636, 681, 764, 188 |
| 2 | 318, 681, 382, 94 |
| 3 | 159, 681, 191, 47 |
| 53, 227, 191, 47 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 53 x 227 x 191 x 47 = 1296027444
Therefore, the lowest common multiple of 636,681,764,188 is 1296027444.
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.
636 x 681 x 764 x 188 = 62209317312
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.
636 : 1, 2, 3, 4, 6, 12, 53, 106, 159, 212, 318, 636
681 : 1, 3, 227, 681
764 : 1, 2, 4, 191, 382, 764
188 : 1, 2, 4, 47, 94, 188
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 636,681,764,188, is 1.
Now, the common factors can be found like this.
636:2x 2x 3x 53
681:3x 227
764:2x 2x 191
188:2x 2x 47
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 2x 2x 3 = 48
Therefore, the value for common factors is 48.
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 = 62209317312/(1x48)
LCM = 62209317312/48
LCM = 1296027444
Thus, we can understand that the LCM of 636,681,764,188 is 1296027444.
