Given numbers are 742,767,533,221

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

The LCM of 742,767,533,221 is 396672458.

Find LCM of 742,767,533,221 with Prime Factorization

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

13 x 742 x 59 x 41 x 17 = 396672458

Therefore, the lowest common multiple of 742,767,533,221 is 396672458.

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 767 x 533 x 221 = 67037645402

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

767 : 1, 13, 59, 767

533 : 1, 13, 41, 533

221 : 1, 13, 17, 221

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 742,767,533,221, is 1.

Now, the common factors can be found like this.

742:2x 7x 53

767:13x 59

533:13x 41

221:13x 17

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

13x 13 = 169

Therefore, the value for common factors is 169.

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 = 67037645402/(1x169)

LCM = 67037645402/169

LCM = 396672458

Thus, we can understand that the LCM of 742,767,533,221 is 396672458.
