Given numbers are 785,772,121,784

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

The LCM of 785,772,121,784 is 14372370320.

Find LCM of 785,772,121,784 with Prime Factorization

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

2 x 2 x 785 x 193 x 121 x 196 = 14372370320

Therefore, the lowest common multiple of 785,772,121,784 is 14372370320.

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.

785 x 772 x 121 x 784 = 57489481280

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.

785 : 1, 5, 157, 785

772 : 1, 2, 4, 193, 386, 772

121 : 1, 11, 121

784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 785,772,121,784, is 1.

Now, the common factors can be found like this.

785:5x 157

772:2x 2x 193

121:11x 11

784:2x 2x 2x 2x 7x 7

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 57489481280/(1x4)

LCM = 57489481280/4

LCM = 14372370320

Thus, we can understand that the LCM of 785,772,121,784 is 14372370320.
