Find LCM of 784,400,582,746,615 with Prime Factorization
2 | 784, 400, 582, 746, 615 |
2 | 392, 200, 291, 373, 615 |
2 | 196, 100, 291, 373, 615 |
2 | 98, 50, 291, 373, 615 |
3 | 49, 25, 291, 373, 615 |
5 | 49, 25, 97, 373, 205 |
49, 5, 97, 373, 41 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 5 x 49 x 5 x 97 x 373 x 41 = 87225154800
Therefore, the lowest common multiple of 784,400,582,746,615 is 87225154800.
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.
784 x 400 x 582 x 746 x 615 = 83736148608000
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.
784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784
400 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 40, 50, 80, 100, 200, 400
582 : 1, 2, 3, 6, 97, 194, 291, 582
746 : 1, 2, 373, 746
615 : 1, 3, 5, 15, 41, 123, 205, 615
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 784,400,582,746,615, is 1.
Now, the common factors can be found like this.
784:2x 2x 2x 2x 7x 7
400:2x 2x 2x 2x 5x 5
582:2x 3x 97
746:2x 373
615:3x 5x 41
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 2x 2x 3x 5 = 960
Therefore, the value for common factors is 960.
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 = 83736148608000/(1x960)
LCM = 83736148608000/960
LCM = 87225154800
Thus, we can understand that the LCM of 784,400,582,746,615 is 87225154800.
