Given numbers are 679,97,140

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 679,97,140 is 13580.

Find LCM of 679,97,140 with Prime Factorization

Multiply the prime numbers at the bottom and the left side.

7 x 97 x 1 x 1 x 20 = 13580

Therefore, the lowest common multiple of 679,97,140 is 13580.

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.

679 x 97 x 140 = 9220820

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.

679 : 1, 7, 97, 679

97 : 1, 97

140 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 70, 140

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 679,97,140, is 1.

Now, the common factors can be found like this.

679:7x 97

97:97

140:2x 2x 5x 7

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

7x 97 = 679

Therefore, the value for common factors is 679.

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 = 9220820/(1x679)

LCM = 9220820/679

LCM = 13580

Thus, we can understand that the LCM of 679,97,140 is 13580.

Here are some samples of LCM of two or more Numbers calculations.

• LCM of 753, 86, 636
• LCM of 181, 92, 642
