Given numbers are 401,772,746,639

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

The LCM of 401,772,746,639 is 73785557484.

Find LCM of 401,772,746,639 with Prime Factorization

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

2 x 401 x 386 x 373 x 639 = 73785557484

Therefore, the lowest common multiple of 401,772,746,639 is 73785557484.

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.

401 x 772 x 746 x 639 = 147571114968

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.

401 : 1, 401

772 : 1, 2, 4, 193, 386, 772

746 : 1, 2, 373, 746

639 : 1, 3, 9, 71, 213, 639

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 401,772,746,639, is 1.

Now, the common factors can be found like this.

401:401

772:2x 2x 193

746:2x 373

639:3x 3x 71

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 = 147571114968/(1x2)

LCM = 147571114968/2

LCM = 73785557484

Thus, we can understand that the LCM of 401,772,746,639 is 73785557484.
