Calculate the LCM of 421,421,724,690,782

Given numbers are 421,421,724,690,782

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

The LCM of 421,421,724,690,782 is 1787675460.

Find LCM of 421,421,724,690,782 with Prime Factorization


2 421, 421, 724, 690, 782
23 421, 421, 362, 345, 391
421 421, 421, 362, 15, 17
1, 1, 362, 15, 17

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

2 x 23 x 421 x 1 x 1 x 362 x 15 x 17 = 1787675460

Therefore, the lowest common multiple of 421,421,724,690,782 is 1787675460.

LCM Formula to Find Lowest Common Multiple of 421,421,724,690,782

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.

421 x 421 x 724 x 690 x 782 = 69240245916720

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.

421 : 1, 421

421 : 1, 421

724 : 1, 2, 4, 181, 362, 724

690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690

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 421,421,724,690,782, is 1.

Now, the common factors can be found like this.

421:421

421:421

724:2x 2x 181

690:2x 3x 5x 23

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 2x 23x 421 = 38732

Therefore, the value for common factors is 38732.

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 = 69240245916720/(1x38732)

LCM = 69240245916720/38732

LCM = 1787675460

Thus, we can understand that the LCM of 421,421,724,690,782 is 1787675460.
