LCM Formula to Find Lowest Common Multiple of 784,114,609,486,972

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 114 x 609 x 486 x 972 = 25712289001728

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

114 : 1, 2, 3, 6, 19, 38, 57, 114

609 : 1, 3, 7, 21, 29, 87, 203, 609

486 : 1, 2, 3, 6, 9, 18, 27, 54, 81, 162, 243, 486

972 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 243, 324, 486, 972

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 784,114,609,486,972, is 1.

Now, the common factors can be found like this.

784:2x 2x 2x 2x 7x 7

114:2x 3x 19

609:3x 7x 29

486:2x 3x 3x 3x 3x 3

972:2x 2x 3x 3x 3x 3x 3

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 3x 3x 3x 3x 3x 3x 3x 7 = 244944

Therefore, the value for common factors is 244944.

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 = 25712289001728/(1x244944)

LCM = 25712289001728/244944

LCM = 104972112

Thus, we can understand that the LCM of 784,114,609,486,972 is 104972112.
