Given numbers are 742,889,170,201

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

The LCM of 742,889,170,201 is 1609987890.

Find LCM of 742,889,170,201 with Prime Factorization

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

2 x 7 x 53 x 127 x 85 x 201 = 1609987890

Therefore, the lowest common multiple of 742,889,170,201 is 1609987890.

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.

742 x 889 x 170 x 201 = 22539830460

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.

742 : 1, 2, 7, 14, 53, 106, 371, 742

889 : 1, 7, 127, 889

170 : 1, 2, 5, 10, 17, 34, 85, 170

201 : 1, 3, 67, 201

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 742,889,170,201, is 1.

Now, the common factors can be found like this.

742:2x 7x 53

889:7x 127

170:2x 5x 17

201:3x 67

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

2x 7 = 14

Therefore, the value for common factors is 14.

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 = 22539830460/(1x14)

LCM = 22539830460/14

LCM = 1609987890

Thus, we can understand that the LCM of 742,889,170,201 is 1609987890.
