Find LCM of 896,190,647,680,685 with Prime Factorization


2 896, 190, 647, 680, 685
2 448, 95, 647, 340, 685
2 224, 95, 647, 170, 685
5 112, 95, 647, 85, 685
112, 19, 647, 17, 137

Multiply the prime numbers at the bottom and the left side.

2 x 2 x 2 x 5 x 112 x 19 x 647 x 17 x 137 = 128264178560

Therefore, the lowest common multiple of 896,190,647,680,685 is 128264178560.

LCM Formula to Find Lowest Common Multiple of 896,190,647,680,685

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.

896 x 190 x 647 x 680 x 685 = 51305671424000

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.

896 : 1, 2, 4, 7, 8, 14, 16, 28, 32, 56, 64, 112, 128, 224, 448, 896

190 : 1, 2, 5, 10, 19, 38, 95, 190

647 : 1, 647

680 : 1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, 680

685 : 1, 5, 137, 685

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 896,190,647,680,685, is 1.

Now, the common factors can be found like this.

896:2x 2x 2x 2x 2x 2x 2x 7

190:2x 5x 19

647:647

680:2x 2x 2x 5x 17

685:5x 137

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 5x 5 = 400

Therefore, the value for common factors is 400.

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 = 51305671424000/(1x400)

LCM = 51305671424000/400

LCM = 128264178560

Thus, we can understand that the LCM of 896,190,647,680,685 is 128264178560.
