Calculate the LCM of 109,170,762,721

Given numbers are 109,170,762,721

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

The LCM of 109,170,762,721 is 5090209530.

Find LCM of 109,170,762,721 with Prime Factorization


2 109, 170, 762, 721
109, 85, 381, 721

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

2 x 109 x 85 x 381 x 721 = 5090209530

Therefore, the lowest common multiple of 109,170,762,721 is 5090209530.

LCM Formula to Find Lowest Common Multiple of 109,170,762,721

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.

109 x 170 x 762 x 721 = 10180419060

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.

109 : 1, 109

170 : 1, 2, 5, 10, 17, 34, 85, 170

762 : 1, 2, 3, 6, 127, 254, 381, 762

721 : 1, 7, 103, 721

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 109,170,762,721, is 1.

Now, the common factors can be found like this.

109:109

170:2x 5x 17

762:2x 3x 127

721:7x 103

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

2 = 2

Therefore, the value for common factors is 2.

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 = 10180419060/(1x2)

LCM = 10180419060/2

LCM = 5090209530

Thus, we can understand that the LCM of 109,170,762,721 is 5090209530.
