Given numbers are 757,842,121,570

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

The LCM of 757,842,121,570 is 21980532090.

Find LCM of 757,842,121,570 with Prime Factorization

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

2 x 757 x 421 x 121 x 285 = 21980532090

Therefore, the lowest common multiple of 757,842,121,570 is 21980532090.

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.

757 x 842 x 121 x 570 = 43961064180

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.

757 : 1, 757

842 : 1, 2, 421, 842

121 : 1, 11, 121

570 : 1, 2, 3, 5, 6, 10, 15, 19, 30, 38, 57, 95, 114, 190, 285, 570

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 757,842,121,570, is 1.

Now, the common factors can be found like this.

757:757

842:2x 421

121:11x 11

570:2x 3x 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 = 43961064180/(1x2)

LCM = 43961064180/2

LCM = 21980532090

Thus, we can understand that the LCM of 757,842,121,570 is 21980532090.
