LCM Formula to Find Lowest Common Multiple of 690,801,631,420,679

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.

690 x 801 x 631 x 420 x 679 = 99455780680200

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.

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

801 : 1, 3, 9, 89, 267, 801

631 : 1, 631

420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420

679 : 1, 7, 97, 679

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 690,801,631,420,679, is 1.

Now, the common factors can be found like this.

690:2x 3x 5x 23

801:3x 3x 89

631:631

420:2x 2x 3x 5x 7

679:7x 97

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 5x 7 = 630

Therefore, the value for common factors is 630.

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 = 99455780680200/(1x630)

LCM = 99455780680200/630

LCM = 157866318540

Thus, we can understand that the LCM of 690,801,631,420,679 is 157866318540.
