Given numbers are 620,905,738,103

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

The LCM of 620,905,738,103 is 4265145540.

Find LCM of 620,905,738,103 with Prime Factorization

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

2 x 5 x 62 x 181 x 369 x 103 = 4265145540

Therefore, the lowest common multiple of 620,905,738,103 is 4265145540.

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 905 x 738 x 103 = 42651455400

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

905 : 1, 5, 181, 905

738 : 1, 2, 3, 6, 9, 18, 41, 82, 123, 246, 369, 738

103 : 1, 103

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 620,905,738,103, is 1.

Now, the common factors can be found like this.

620:2x 2x 5x 31

905:5x 181

738:2x 3x 3x 41

103:103

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

2x 5 = 10

Therefore, the value for common factors is 10.

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 = 42651455400/(1x10)

LCM = 42651455400/10

LCM = 4265145540

Thus, we can understand that the LCM of 620,905,738,103 is 4265145540.
