Calculate the LCM of 621,641,760,745

Given numbers are 621,641,760,745

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

The LCM of 621,641,760,745 is 45076427640.

Find LCM of 621,641,760,745 with Prime Factorization


5 621, 641, 760, 745
621, 641, 152, 149

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

5 x 621 x 641 x 152 x 149 = 45076427640

Therefore, the lowest common multiple of 621,641,760,745 is 45076427640.

LCM Formula to Find Lowest Common Multiple of 621,641,760,745

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.

621 x 641 x 760 x 745 = 225382138200

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.

621 : 1, 3, 9, 23, 27, 69, 207, 621

641 : 1, 641

760 : 1, 2, 4, 5, 8, 10, 19, 20, 38, 40, 76, 95, 152, 190, 380, 760

745 : 1, 5, 149, 745

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 621,641,760,745, is 1.

Now, the common factors can be found like this.

621:3x 3x 3x 23

641:641

760:2x 2x 2x 5x 19

745:5x 149

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

5 = 5

Therefore, the value for common factors is 5.

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 = 225382138200/(1x5)

LCM = 225382138200/5

LCM = 45076427640

Thus, we can understand that the LCM of 621,641,760,745 is 45076427640.
