Given numbers are 840,761,761

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

The LCM of 840,761,761 is 639240.

Find LCM of 840,761,761 with Prime Factorization

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

761 x 840 x 1 x 1 = 639240

Therefore, the lowest common multiple of 840,761,761 is 639240.

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.

840 x 761 x 761 = 486461640

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.

840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840

761 : 1, 761

761 : 1, 761

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 840,761,761, is 1.

Now, the common factors can be found like this.

840:2x 2x 2x 3x 5x 7

761:761

761:761

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

761 = 761

Therefore, the value for common factors is 761.

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 = 486461640/(1x761)

LCM = 486461640/761

LCM = 639240

Thus, we can understand that the LCM of 840,761,761 is 639240.

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

• LCM of 158, 960, 369
