LCM Formula to Find Lowest Common Multiple of 972,618,690,126,882

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 618 x 690 x 126 x 882 = 46062018031680

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

618 : 1, 2, 3, 6, 103, 206, 309, 618

690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690

126 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 42, 63, 126

882 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 42, 49, 63, 98, 126, 147, 294, 441, 882

6 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 972,618,690,126,882, is 6.

Now, the common factors can be found like this.

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

618:2x 3x 103

690:2x 3x 5x 23

126:2x 3x 3x 7

882:2x 3x 3x 7x 7

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 3x 3x 3x 3x 3x 7 = 13608

Therefore, the value for common factors is 13608.

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 = 46062018031680/(6x13608)

LCM = 46062018031680/81648

LCM = 564153660

Thus, we can understand that the LCM of 972,618,690,126,882 is 564153660.
