Calculate the LCM of 471,137,143,685

Given numbers are 471,137,143,685

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

The LCM of 471,137,143,685 is 46136805.

Find LCM of 471,137,143,685 with Prime Factorization


137 471, 137, 143, 685
471, 1, 143, 5

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

137 x 471 x 1 x 143 x 5 = 46136805

Therefore, the lowest common multiple of 471,137,143,685 is 46136805.

LCM Formula to Find Lowest Common Multiple of 471,137,143,685

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.

471 x 137 x 143 x 685 = 6320742285

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.

471 : 1, 3, 157, 471

137 : 1, 137

143 : 1, 11, 13, 143

685 : 1, 5, 137, 685

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 471,137,143,685, is 1.

Now, the common factors can be found like this.

471:3x 157

137:137

143:11x 13

685:5x 137

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

137 = 137

Therefore, the value for common factors is 137.

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 = 6320742285/(1x137)

LCM = 6320742285/137

LCM = 46136805

Thus, we can understand that the LCM of 471,137,143,685 is 46136805.
