Given numbers are 661,438,273,746

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

The LCM of 661,438,273,746 is 9827109474.

Find LCM of 661,438,273,746 with Prime Factorization

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

2 x 3 x 661 x 73 x 91 x 373 = 9827109474

Therefore, the lowest common multiple of 661,438,273,746 is 9827109474.

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.

661 x 438 x 273 x 746 = 58962656844

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.

661 : 1, 661

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

273 : 1, 3, 7, 13, 21, 39, 91, 273

746 : 1, 2, 373, 746

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 661,438,273,746, is 1.

Now, the common factors can be found like this.

661:661

438:2x 3x 73

273:3x 7x 13

746:2x 373

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

2x 3 = 6

Therefore, the value for common factors is 6.

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 = 58962656844/(1x6)

LCM = 58962656844/6

LCM = 9827109474

Thus, we can understand that the LCM of 661,438,273,746 is 9827109474.
