Calculate the LCM of 920,740,109,668

Given numbers are 920,740,109,668

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

The LCM of 920,740,109,668 is 619630120.

Find LCM of 920,740,109,668 with Prime Factorization


2 920, 740, 109, 668
2 460, 370, 109, 334
5 230, 185, 109, 167
46, 37, 109, 167

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

2 x 2 x 5 x 46 x 37 x 109 x 167 = 619630120

Therefore, the lowest common multiple of 920,740,109,668 is 619630120.

LCM Formula to Find Lowest Common Multiple of 920,740,109,668

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.

920 x 740 x 109 x 668 = 49570409600

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.

920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920

740 : 1, 2, 4, 5, 10, 20, 37, 74, 148, 185, 370, 740

109 : 1, 109

668 : 1, 2, 4, 167, 334, 668

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 920,740,109,668, is 1.

Now, the common factors can be found like this.

920:2x 2x 2x 5x 23

740:2x 2x 5x 37

109:109

668:2x 2x 167

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

2x 2x 2x 2x 5 = 80

Therefore, the value for common factors is 80.

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 = 49570409600/(1x80)

LCM = 49570409600/80

LCM = 619630120

Thus, we can understand that the LCM of 920,740,109,668 is 619630120.
