Calculate the LCM of 714,643,493,782

Given numbers are 714,643,493,782

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

The LCM of 714,643,493,782 is 306221034.

Find LCM of 714,643,493,782 with Prime Factorization


2 714, 643, 493, 782
17 357, 643, 493, 391
21, 643, 29, 23

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

2 x 17 x 21 x 643 x 29 x 23 = 306221034

Therefore, the lowest common multiple of 714,643,493,782 is 306221034.

LCM Formula to Find Lowest Common Multiple of 714,643,493,782

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.

714 x 643 x 493 x 782 = 176995757652

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.

714 : 1, 2, 3, 6, 7, 14, 17, 21, 34, 42, 51, 102, 119, 238, 357, 714

643 : 1, 643

493 : 1, 17, 29, 493

782 : 1, 2, 17, 23, 34, 46, 391, 782

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 714,643,493,782, is 1.

Now, the common factors can be found like this.

714:2x 3x 7x 17

643:643

493:17x 29

782:2x 17x 23

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

2x 17x 17 = 578

Therefore, the value for common factors is 578.

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 = 176995757652/(1x578)

LCM = 176995757652/578

LCM = 306221034

Thus, we can understand that the LCM of 714,643,493,782 is 306221034.
