Given numbers are 742,201,920,661

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

The LCM of 742,201,920,661 is 45348116520.

Find LCM of 742,201,920,661 with Prime Factorization

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

2 x 371 x 201 x 460 x 661 = 45348116520

Therefore, the lowest common multiple of 742,201,920,661 is 45348116520.

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 201 x 920 x 661 = 90696233040

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

201 : 1, 3, 67, 201

920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920

661 : 1, 661

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 742,201,920,661, is 1.

Now, the common factors can be found like this.

742:2x 7x 53

201:3x 67

920:2x 2x 2x 5x 23

661:661

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 = 90696233040/(1x2)

LCM = 90696233040/2

LCM = 45348116520

Thus, we can understand that the LCM of 742,201,920,661 is 45348116520.
