LCM Formula to Find Lowest Common Multiple of 972,705,670,729,653

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.

972 x 705 x 670 x 729 x 653 = 218560106795400

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.

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

705 : 1, 3, 5, 15, 47, 141, 235, 705

670 : 1, 2, 5, 10, 67, 134, 335, 670

729 : 1, 3, 9, 27, 81, 243, 729

653 : 1, 653

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 972,705,670,729,653, is 1.

Now, the common factors can be found like this.

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

705:3x 5x 47

670:2x 5x 67

729:3x 3x 3x 3x 3x 3

653:653

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 3x 3x 3x 3x 3x 5 = 7290

Therefore, the value for common factors is 7290.

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 = 218560106795400/(1x7290)

LCM = 218560106795400/7290

LCM = 29980810260

Thus, we can understand that the LCM of 972,705,670,729,653 is 29980810260.
