Given numbers are 242,178,159,715

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

The LCM of 242,178,159,715 is 222595230.

Find LCM of 242,178,159,715 with Prime Factorization

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

2 x 11 x 11 x 89 x 159 x 65 = 222595230

Therefore, the lowest common multiple of 242,178,159,715 is 222595230.

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.

242 x 178 x 159 x 715 = 4897095060

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.

242 : 1, 2, 11, 22, 121, 242

178 : 1, 2, 89, 178

159 : 1, 3, 53, 159

715 : 1, 5, 11, 13, 55, 65, 143, 715

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 242,178,159,715, is 1.

Now, the common factors can be found like this.

242:2x 11x 11

178:2x 89

159:3x 53

715:5x 11x 13

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

2x 11 = 22

Therefore, the value for common factors is 22.

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 = 4897095060/(1x22)

LCM = 4897095060/22

LCM = 222595230

Thus, we can understand that the LCM of 242,178,159,715 is 222595230.
