LCM Formula to Find Lowest Common Multiple of 959,640,688,987

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.

959 x 640 x 688 x 987 = 416777410560

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.

959 : 1, 7, 137, 959

640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640

688 : 1, 2, 4, 8, 16, 43, 86, 172, 344, 688

987 : 1, 3, 7, 21, 47, 141, 329, 987

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 959,640,688,987, is 1.

Now, the common factors can be found like this.

959:7x 137

640:2x 2x 2x 2x 2x 2x 2x 5

688:2x 2x 2x 2x 43

987:3x 7x 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 7 = 112

Therefore, the value for common factors is 112.

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 = 416777410560/(1x112)

LCM = 416777410560/112

LCM = 3721226880

Thus, we can understand that the LCM of 959,640,688,987 is 3721226880.
