Given numbers are 279,641,641,769

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

The LCM of 279,641,641,769 is 137527191.

Find LCM of 279,641,641,769 with Prime Factorization

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

641 x 279 x 1 x 1 x 769 = 137527191

Therefore, the lowest common multiple of 279,641,641,769 is 137527191.

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.

279 x 641 x 641 x 769 = 88154929431

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.

279 : 1, 3, 9, 31, 93, 279

641 : 1, 641

641 : 1, 641

769 : 1, 769

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 279,641,641,769, is 1.

Now, the common factors can be found like this.

279:3x 3x 31

641:641

641:641

769:769

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

641 = 641

Therefore, the value for common factors is 641.

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 = 88154929431/(1x641)

LCM = 88154929431/641

LCM = 137527191

Thus, we can understand that the LCM of 279,641,641,769 is 137527191.
