Given numbers are 2,978,611,817

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

The LCM of 2,978,611,817 is 488204886.

Find LCM of 2,978,611,817 with Prime Factorization

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

2 x 1 x 489 x 611 x 817 = 488204886

Therefore, the lowest common multiple of 2,978,611,817 is 488204886.

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.

2 x 978 x 611 x 817 = 976409772

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.

2 : 1, 2

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

611 : 1, 13, 47, 611

817 : 1, 19, 43, 817

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 2,978,611,817, is 1.

Now, the common factors can be found like this.

2:2

978:2x 3x 163

611:13x 47

817:19x 43

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 = 976409772/(1x2)

LCM = 976409772/2

LCM = 488204886

Thus, we can understand that the LCM of 2,978,611,817 is 488204886.
