Calculate the LCM of 742,596,408,142,781

Given numbers are 742,596,408,142,781

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

The LCM of 742,596,408,142,781 is 17614542792.

Find LCM of 742,596,408,142,781 with Prime Factorization


2 742, 596, 408, 142, 781
2 371, 298, 204, 71, 781
71 371, 149, 102, 71, 781
371, 149, 102, 1, 11

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

2 x 2 x 71 x 371 x 149 x 102 x 1 x 11 = 17614542792

Therefore, the lowest common multiple of 742,596,408,142,781 is 17614542792.

LCM Formula to Find Lowest Common Multiple of 742,596,408,142,781

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.

742 x 596 x 408 x 142 x 781 = 20010120611712

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.

742 : 1, 2, 7, 14, 53, 106, 371, 742

596 : 1, 2, 4, 149, 298, 596

408 : 1, 2, 3, 4, 6, 8, 12, 17, 24, 34, 51, 68, 102, 136, 204, 408

142 : 1, 2, 71, 142

781 : 1, 11, 71, 781

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 742,596,408,142,781, is 1.

Now, the common factors can be found like this.

742:2x 7x 53

596:2x 2x 149

408:2x 2x 2x 3x 17

142:2x 71

781:11x 71

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 2x 2x 71 = 1136

Therefore, the value for common factors is 1136.

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 = 20010120611712/(1x1136)

LCM = 20010120611712/1136

LCM = 17614542792

Thus, we can understand that the LCM of 742,596,408,142,781 is 17614542792.
