Given numbers are 101,253,121,861

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

The LCM of 101,253,121,861 is 242012463.

Find LCM of 101,253,121,861 with Prime Factorization

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

11 x 101 x 23 x 11 x 861 = 242012463

Therefore, the lowest common multiple of 101,253,121,861 is 242012463.

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.

101 x 253 x 121 x 861 = 2662137093

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.

101 : 1, 101

253 : 1, 11, 23, 253

121 : 1, 11, 121

861 : 1, 3, 7, 21, 41, 123, 287, 861

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 101,253,121,861, is 1.

Now, the common factors can be found like this.

101:101

253:11x 23

121:11x 11

861:3x 7x 41

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

11 = 11

Therefore, the value for common factors is 11.

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 = 2662137093/(1x11)

LCM = 2662137093/11

LCM = 242012463

Thus, we can understand that the LCM of 101,253,121,861 is 242012463.
