Given numbers are 921,606,133,978

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

The LCM of 921,606,133,978 is 4033204518.

Find LCM of 921,606,133,978 with Prime Factorization

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

2 x 3 x 307 x 101 x 133 x 163 = 4033204518

Therefore, the lowest common multiple of 921,606,133,978 is 4033204518.

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.

921 x 606 x 133 x 978 = 72597681324

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.

921 : 1, 3, 307, 921

606 : 1, 2, 3, 6, 101, 202, 303, 606

133 : 1, 7, 19, 133

978 : 1, 2, 3, 6, 163, 326, 489, 978

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 921,606,133,978, is 1.

Now, the common factors can be found like this.

921:3x 307

606:2x 3x 101

133:7x 19

978:2x 3x 163

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

2x 3x 3 = 18

Therefore, the value for common factors is 18.

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 = 72597681324/(1x18)

LCM = 72597681324/18

LCM = 4033204518

Thus, we can understand that the LCM of 921,606,133,978 is 4033204518.
