Given numbers are 163,978,221,437

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

The LCM of 163,978,221,437 is 94452306.

Find LCM of 163,978,221,437 with Prime Factorization

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

163 x 1 x 6 x 221 x 437 = 94452306

Therefore, the lowest common multiple of 163,978,221,437 is 94452306.

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.

163 x 978 x 221 x 437 = 15395725878

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.

163 : 1, 163

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

221 : 1, 13, 17, 221

437 : 1, 19, 23, 437

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 163,978,221,437, is 1.

Now, the common factors can be found like this.

163:163

978:2x 3x 163

221:13x 17

437:19x 23

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 = 15395725878/(1x163)

LCM = 15395725878/163

LCM = 94452306

Thus, we can understand that the LCM of 163,978,221,437 is 94452306.
