Calculate the LCM of 406,202,107,749

Given numbers are 406,202,107,749

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

The LCM of 406,202,107,749 is 4387642.

Find LCM of 406,202,107,749 with Prime Factorization


2 406, 202, 107, 749
7 203, 101, 107, 749
107 29, 101, 107, 107
29, 101, 1, 1

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

2 x 7 x 107 x 29 x 101 x 1 x 1 = 4387642

Therefore, the lowest common multiple of 406,202,107,749 is 4387642.

LCM Formula to Find Lowest Common Multiple of 406,202,107,749

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.

406 x 202 x 107 x 749 = 6572687716

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.

406 : 1, 2, 7, 14, 29, 58, 203, 406

202 : 1, 2, 101, 202

107 : 1, 107

749 : 1, 7, 107, 749

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 406,202,107,749, is 1.

Now, the common factors can be found like this.

406:2x 7x 29

202:2x 101

107:107

749:7x 107

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

2x 7x 107 = 1498

Therefore, the value for common factors is 1498.

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 = 6572687716/(1x1498)

LCM = 6572687716/1498

LCM = 4387642

Thus, we can understand that the LCM of 406,202,107,749 is 4387642.
