Given numbers are 645,398,457,266

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

The LCM of 645,398,457,266 is 15603090510.

Find LCM of 645,398,457,266 with Prime Factorization

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

2 x 645 x 199 x 457 x 133 = 15603090510

Therefore, the lowest common multiple of 645,398,457,266 is 15603090510.

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.

645 x 398 x 457 x 266 = 31206181020

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.

645 : 1, 3, 5, 15, 43, 129, 215, 645

398 : 1, 2, 199, 398

457 : 1, 457

266 : 1, 2, 7, 14, 19, 38, 133, 266

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 645,398,457,266, is 1.

Now, the common factors can be found like this.

645:3x 5x 43

398:2x 199

457:457

266:2x 7x 19

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 = 31206181020/(1x2)

LCM = 31206181020/2

LCM = 15603090510

Thus, we can understand that the LCM of 645,398,457,266 is 15603090510.
