Given numbers are 620,660,440,973,944

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

The LCM of 620,660,440,973,944 is 4698188880.

Find LCM of 620,660,440,973,944 with Prime Factorization

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

2 x 2 x 2 x 5 x 11 x 31 x 3 x 1 x 973 x 118 = 4698188880

Therefore, the lowest common multiple of 620,660,440,973,944 is 4698188880.

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.

620 x 660 x 440 x 973 x 944 = 165376248576000

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.

620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620

660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660

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

973 : 1, 7, 139, 973

944 : 1, 2, 4, 8, 16, 59, 118, 236, 472, 944

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 620,660,440,973,944, is 1.

Now, the common factors can be found like this.

620:2x 2x 5x 31

660:2x 2x 3x 5x 11

440:2x 2x 2x 5x 11

973:7x 139

944:2x 2x 2x 2x 59

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 2x 2x 2x 5x 5x 11 = 35200

Therefore, the value for common factors is 35200.

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 = 165376248576000/(1x35200)

LCM = 165376248576000/35200

LCM = 4698188880

Thus, we can understand that the LCM of 620,660,440,973,944 is 4698188880.
