Calculate the LCM of 428,721,830,151,629

Given numbers are 428,721,830,151,629

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

The LCM of 428,721,830,151,629 is 12163392555580.

Find LCM of 428,721,830,151,629 with Prime Factorization


2 428, 721, 830, 151, 629
214, 721, 415, 151, 629

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

2 x 214 x 721 x 415 x 151 x 629 = 12163392555580

Therefore, the lowest common multiple of 428,721,830,151,629 is 12163392555580.

LCM Formula to Find Lowest Common Multiple of 428,721,830,151,629

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.

428 x 721 x 830 x 151 x 629 = 24326785111160

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.

428 : 1, 2, 4, 107, 214, 428

721 : 1, 7, 103, 721

830 : 1, 2, 5, 10, 83, 166, 415, 830

151 : 1, 151

629 : 1, 17, 37, 629

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 428,721,830,151,629, is 1.

Now, the common factors can be found like this.

428:2x 2x 107

721:7x 103

830:2x 5x 83

151:151

629:17x 37

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 = 24326785111160/(1x2)

LCM = 24326785111160/2

LCM = 12163392555580

Thus, we can understand that the LCM of 428,721,830,151,629 is 12163392555580.
