Given numbers are 221,658,157,644

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

The LCM of 221,658,157,644 is 1050208796.

Find LCM of 221,658,157,644 with Prime Factorization

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

2 x 7 x 221 x 47 x 157 x 46 = 1050208796

Therefore, the lowest common multiple of 221,658,157,644 is 1050208796.

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.

221 x 658 x 157 x 644 = 14702923144

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.

221 : 1, 13, 17, 221

658 : 1, 2, 7, 14, 47, 94, 329, 658

157 : 1, 157

644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 221,658,157,644, is 1.

Now, the common factors can be found like this.

221:13x 17

658:2x 7x 47

157:157

644:2x 2x 7x 23

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

2x 7 = 14

Therefore, the value for common factors is 14.

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 = 14702923144/(1x14)

LCM = 14702923144/14

LCM = 1050208796

Thus, we can understand that the LCM of 221,658,157,644 is 1050208796.
