Given numbers are 487,978,980

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

The LCM of 487,978,980 is 233380140.

Find LCM of 487,978,980 with Prime Factorization

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

2 x 487 x 489 x 490 = 233380140

Therefore, the lowest common multiple of 487,978,980 is 233380140.

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.

487 x 978 x 980 = 466760280

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.

487 : 1, 487

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

980 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 49, 70, 98, 140, 196, 245, 490, 980

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 487,978,980, is 1.

Now, the common factors can be found like this.

487:487

978:2x 3x 163

980:2x 2x 5x 7x 7

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

2 = 2

Therefore, the value for common factors is 2.

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 = 466760280/(1x2)

LCM = 466760280/2

LCM = 233380140

Thus, we can understand that the LCM of 487,978,980 is 233380140.
