Given numbers are 290,986,987,478

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

The LCM of 290,986,987,478 is 1162952490.

Find LCM of 290,986,987,478 with Prime Factorization

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

2 x 29 x 5 x 17 x 987 x 239 = 1162952490

Therefore, the lowest common multiple of 290,986,987,478 is 1162952490.

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.

290 x 986 x 987 x 478 = 134902488840

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.

290 : 1, 2, 5, 10, 29, 58, 145, 290

986 : 1, 2, 17, 29, 34, 58, 493, 986

987 : 1, 3, 7, 21, 47, 141, 329, 987

478 : 1, 2, 239, 478

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 290,986,987,478, is 1.

Now, the common factors can be found like this.

290:2x 5x 29

986:2x 17x 29

987:3x 7x 47

478:2x 239

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

2x 2x 29 = 116

Therefore, the value for common factors is 116.

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 = 134902488840/(1x116)

LCM = 134902488840/116

LCM = 1162952490

Thus, we can understand that the LCM of 290,986,987,478 is 1162952490.
