Given numbers are 154,771,201,438

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

The LCM of 154,771,201,438 is 580727994.

Find LCM of 154,771,201,438 with Prime Factorization

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

2 x 3 x 77 x 257 x 67 x 73 = 580727994

Therefore, the lowest common multiple of 154,771,201,438 is 580727994.

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.

154 x 771 x 201 x 438 = 10453103892

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.

154 : 1, 2, 7, 11, 14, 22, 77, 154

771 : 1, 3, 257, 771

201 : 1, 3, 67, 201

438 : 1, 2, 3, 6, 73, 146, 219, 438

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 154,771,201,438, is 1.

Now, the common factors can be found like this.

154:2x 7x 11

771:3x 257

201:3x 67

438:2x 3x 73

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 = 10453103892/(1x18)

LCM = 10453103892/18

LCM = 580727994

Thus, we can understand that the LCM of 154,771,201,438 is 580727994.
