Given numbers are 610,668,409,978

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

The LCM of 610,668,409,978 is 40748203740.

Find LCM of 610,668,409,978 with Prime Factorization

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

2 x 305 x 334 x 409 x 489 = 40748203740

Therefore, the lowest common multiple of 610,668,409,978 is 40748203740.

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.

610 x 668 x 409 x 978 = 162992814960

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.

610 : 1, 2, 5, 10, 61, 122, 305, 610

668 : 1, 2, 4, 167, 334, 668

409 : 1, 409

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 610,668,409,978, is 1.

Now, the common factors can be found like this.

610:2x 5x 61

668:2x 2x 167

409:409

978:2x 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 2 = 4

Therefore, the value for common factors is 4.

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 = 162992814960/(1x4)

LCM = 162992814960/4

LCM = 40748203740

Thus, we can understand that the LCM of 610,668,409,978 is 40748203740.
