Calculate the LCM of 781,372,143,281

Given numbers are 781,372,143,281

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

The LCM of 781,372,143,281 is 1061313396.

Find LCM of 781,372,143,281 with Prime Factorization


11 781, 372, 143, 281
71, 372, 13, 281

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

11 x 71 x 372 x 13 x 281 = 1061313396

Therefore, the lowest common multiple of 781,372,143,281 is 1061313396.

LCM Formula to Find Lowest Common Multiple of 781,372,143,281

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.

781 x 372 x 143 x 281 = 11674447356

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.

781 : 1, 11, 71, 781

372 : 1, 2, 3, 4, 6, 12, 31, 62, 93, 124, 186, 372

143 : 1, 11, 13, 143

281 : 1, 281

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 781,372,143,281, is 1.

Now, the common factors can be found like this.

781:11x 71

372:2x 2x 3x 31

143:11x 13

281:281

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

11 = 11

Therefore, the value for common factors is 11.

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 = 11674447356/(1x11)

LCM = 11674447356/11

LCM = 1061313396

Thus, we can understand that the LCM of 781,372,143,281 is 1061313396.
