Given numbers are 402,218,235,661

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

The LCM of 402,218,235,661 is 6806469030.

Find LCM of 402,218,235,661 with Prime Factorization

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

2 x 201 x 109 x 235 x 661 = 6806469030

Therefore, the lowest common multiple of 402,218,235,661 is 6806469030.

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.

402 x 218 x 235 x 661 = 13612938060

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.

402 : 1, 2, 3, 6, 67, 134, 201, 402

218 : 1, 2, 109, 218

235 : 1, 5, 47, 235

661 : 1, 661

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 402,218,235,661, is 1.

Now, the common factors can be found like this.

402:2x 3x 67

218:2x 109

235:5x 47

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 = 13612938060/(1x2)

LCM = 13612938060/2

LCM = 6806469030

Thus, we can understand that the LCM of 402,218,235,661 is 6806469030.
