Given numbers are 140,177,102,489

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

The LCM of 140,177,102,489 is 68665380.

Find LCM of 140,177,102,489 with Prime Factorization

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

2 x 3 x 70 x 59 x 17 x 163 = 68665380

Therefore, the lowest common multiple of 140,177,102,489 is 68665380.

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.

140 x 177 x 102 x 489 = 1235976840

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.

140 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 70, 140

177 : 1, 3, 59, 177

102 : 1, 2, 3, 6, 17, 34, 51, 102

489 : 1, 3, 163, 489

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 140,177,102,489, is 1.

Now, the common factors can be found like this.

140:2x 2x 5x 7

177:3x 59

102:2x 3x 17

489:3x 163

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

2x 3x 3 = 18

Therefore, the value for common factors is 18.

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 = 1235976840/(1x18)

LCM = 1235976840/18

LCM = 68665380

Thus, we can understand that the LCM of 140,177,102,489 is 68665380.
