Calculate the LCM of 783,761,446,403,380

Given numbers are 783,761,446,403,380

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

The LCM of 783,761,446,403,380 is 20348852539860.

Find LCM of 783,761,446,403,380 with Prime Factorization


2 783, 761, 446, 403, 380
783, 761, 223, 403, 190

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

2 x 783 x 761 x 223 x 403 x 190 = 20348852539860

Therefore, the lowest common multiple of 783,761,446,403,380 is 20348852539860.

LCM Formula to Find Lowest Common Multiple of 783,761,446,403,380

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.

783 x 761 x 446 x 403 x 380 = 40697705079720

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.

783 : 1, 3, 9, 27, 29, 87, 261, 783

761 : 1, 761

446 : 1, 2, 223, 446

403 : 1, 13, 31, 403

380 : 1, 2, 4, 5, 10, 19, 20, 38, 76, 95, 190, 380

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 783,761,446,403,380, is 1.

Now, the common factors can be found like this.

783:3x 3x 3x 29

761:761

446:2x 223

403:13x 31

380:2x 2x 5x 19

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

2 = 2

Therefore, the value for common factors is 2.

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 = 40697705079720/(1x2)

LCM = 40697705079720/2

LCM = 20348852539860

Thus, we can understand that the LCM of 783,761,446,403,380 is 20348852539860.
