Given numbers are 781,942,141,742

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

The LCM of 781,942,141,742 is 12828435774.

Find LCM of 781,942,141,742 with Prime Factorization

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

2 x 3 x 781 x 157 x 47 x 371 = 12828435774

Therefore, the lowest common multiple of 781,942,141,742 is 12828435774.

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 942 x 141 x 742 = 76970614644

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

942 : 1, 2, 3, 6, 157, 314, 471, 942

141 : 1, 3, 47, 141

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 781,942,141,742, is 1.

Now, the common factors can be found like this.

781:11x 71

942:2x 3x 157

141:3x 47

742:2x 7x 53

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

2x 3 = 6

Therefore, the value for common factors is 6.

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 = 76970614644/(1x6)

LCM = 76970614644/6

LCM = 12828435774

Thus, we can understand that the LCM of 781,942,141,742 is 12828435774.
