Given numbers are 403,713,752,421

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

The LCM of 403,713,752,421 is 2934491248.

Find LCM of 403,713,752,421 with Prime Factorization

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

31 x 13 x 23 x 752 x 421 = 2934491248

Therefore, the lowest common multiple of 403,713,752,421 is 2934491248.

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.

403 x 713 x 752 x 421 = 90969228688

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.

403 : 1, 13, 31, 403

713 : 1, 23, 31, 713

752 : 1, 2, 4, 8, 16, 47, 94, 188, 376, 752

421 : 1, 421

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 403,713,752,421, is 1.

Now, the common factors can be found like this.

403:13x 31

713:23x 31

752:2x 2x 2x 2x 47

421:421

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

31 = 31

Therefore, the value for common factors is 31.

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 = 90969228688/(1x31)

LCM = 90969228688/31

LCM = 2934491248

Thus, we can understand that the LCM of 403,713,752,421 is 2934491248.
