Given numbers are 161,163,978,751

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

The LCM of 161,163,978,751 is 118250958.

Find LCM of 161,163,978,751 with Prime Factorization

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

163 x 161 x 1 x 6 x 751 = 118250958

Therefore, the lowest common multiple of 161,163,978,751 is 118250958.

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.

161 x 163 x 978 x 751 = 19274906154

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.

161 : 1, 7, 23, 161

163 : 1, 163

978 : 1, 2, 3, 6, 163, 326, 489, 978

751 : 1, 751

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 161,163,978,751, is 1.

Now, the common factors can be found like this.

161:7x 23

163:163

978:2x 3x 163

751:751

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

163 = 163

Therefore, the value for common factors is 163.

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 = 19274906154/(1x163)

LCM = 19274906154/163

LCM = 118250958

Thus, we can understand that the LCM of 161,163,978,751 is 118250958.
