Given numbers are 642,264,983,753
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 642,264,983,753 is 6969713784.
Find LCM of 642,264,983,753 with Prime Factorization
2 | 642, 264, 983, 753 |
3 | 321, 132, 983, 753 |
107, 44, 983, 251 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 107 x 44 x 983 x 251 = 6969713784
Therefore, the lowest common multiple of 642,264,983,753 is 6969713784.
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.
642 x 264 x 983 x 753 = 125454848112
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.
642 : 1, 2, 3, 6, 107, 214, 321, 642
264 : 1, 2, 3, 4, 6, 8, 11, 12, 22, 24, 33, 44, 66, 88, 132, 264
983 : 1, 983
753 : 1, 3, 251, 753
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 642,264,983,753, is 1.
Now, the common factors can be found like this.
642:2x 3x 107
264:2x 2x 2x 3x 11
983:983
753:3x 251
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 3 = 18
Therefore, the value for common factors is 18.
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 = 125454848112/(1x18)
LCM = 125454848112/18
LCM = 6969713784
Thus, we can understand that the LCM of 642,264,983,753 is 6969713784.
