Given numbers are 615,983,690,628
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 615,983,690,628 is 8732047980.
Find LCM of 615,983,690,628 with Prime Factorization
2 | 615, 983, 690, 628 |
3 | 615, 983, 345, 314 |
5 | 205, 983, 115, 314 |
41, 983, 23, 314 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 41 x 983 x 23 x 314 = 8732047980
Therefore, the lowest common multiple of 615,983,690,628 is 8732047980.
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.
615 x 983 x 690 x 628 = 261961439400
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.
615 : 1, 3, 5, 15, 41, 123, 205, 615
983 : 1, 983
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
628 : 1, 2, 4, 157, 314, 628
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 615,983,690,628, is 1.
Now, the common factors can be found like this.
615:3x 5x 41
983:983
690:2x 3x 5x 23
628:2x 2x 157
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 5 = 30
Therefore, the value for common factors is 30.
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 = 261961439400/(1x30)
LCM = 261961439400/30
LCM = 8732047980
Thus, we can understand that the LCM of 615,983,690,628 is 8732047980.
