Given numbers are 671,740,880,980

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

The LCM of 671,740,880,980 is 97321840.

Find LCM of 671,740,880,980 with Prime Factorization

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

2 x 2 x 5 x 11 x 61 x 37 x 4 x 49 = 97321840

Therefore, the lowest common multiple of 671,740,880,980 is 97321840.

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.

671 x 740 x 880 x 980 = 428216096000

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.

671 : 1, 11, 61, 671

740 : 1, 2, 4, 5, 10, 20, 37, 74, 148, 185, 370, 740

880 : 1, 2, 4, 5, 8, 10, 11, 16, 20, 22, 40, 44, 55, 80, 88, 110, 176, 220, 440, 880

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 671,740,880,980, is 1.

Now, the common factors can be found like this.

671:11x 61

740:2x 2x 5x 37

880:2x 2x 2x 2x 5x 11

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.

2x 2x 2x 2x 5x 5x 11 = 4400

Therefore, the value for common factors is 4400.

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 = 428216096000/(1x4400)

LCM = 428216096000/4400

LCM = 97321840

Thus, we can understand that the LCM of 671,740,880,980 is 97321840.
