Calculate the LCM of 700,728,399,743

Given numbers are 700,728,399,743

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

The LCM of 700,728,399,743 is 770788200.

Find LCM of 700,728,399,743 with Prime Factorization


2 700, 728, 399, 743
2 350, 364, 399, 743
7 175, 182, 399, 743
25, 26, 57, 743

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

2 x 2 x 7 x 25 x 26 x 57 x 743 = 770788200

Therefore, the lowest common multiple of 700,728,399,743 is 770788200.

LCM Formula to Find Lowest Common Multiple of 700,728,399,743

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.

700 x 728 x 399 x 743 = 151074487200

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.

700 : 1, 2, 4, 5, 7, 10, 14, 20, 25, 28, 35, 50, 70, 100, 140, 175, 350, 700

728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728

399 : 1, 3, 7, 19, 21, 57, 133, 399

743 : 1, 743

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 700,728,399,743, is 1.

Now, the common factors can be found like this.

700:2x 2x 5x 5x 7

728:2x 2x 2x 7x 13

399:3x 7x 19

743:743

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 7x 7 = 196

Therefore, the value for common factors is 196.

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 = 151074487200/(1x196)

LCM = 151074487200/196

LCM = 770788200

Thus, we can understand that the LCM of 700,728,399,743 is 770788200.
