Calculate the LCM of 429,756,721,575

Given numbers are 429,756,721,575

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

The LCM of 429,756,721,575 is 6402696300.

Find LCM of 429,756,721,575 with Prime Factorization


3 429, 756, 721, 575
7 143, 252, 721, 575
143, 36, 103, 575

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

3 x 7 x 143 x 36 x 103 x 575 = 6402696300

Therefore, the lowest common multiple of 429,756,721,575 is 6402696300.

LCM Formula to Find Lowest Common Multiple of 429,756,721,575

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.

429 x 756 x 721 x 575 = 134456622300

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.

429 : 1, 3, 11, 13, 33, 39, 143, 429

756 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 27, 28, 36, 42, 54, 63, 84, 108, 126, 189, 252, 378, 756

721 : 1, 7, 103, 721

575 : 1, 5, 23, 25, 115, 575

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 429,756,721,575, is 1.

Now, the common factors can be found like this.

429:3x 11x 13

756:2x 2x 3x 3x 3x 7

721:7x 103

575:5x 5x 23

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

3x 7 = 21

Therefore, the value for common factors is 21.

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 = 134456622300/(1x21)

LCM = 134456622300/21

LCM = 6402696300

Thus, we can understand that the LCM of 429,756,721,575 is 6402696300.
