Given numbers are 672,622,221,385,994

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

The LCM of 672,622,221,385,994 is 180361140960.

Find LCM of 672,622,221,385,994 with Prime Factorization

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

2 x 7 x 48 x 311 x 221 x 55 x 71 = 180361140960

Therefore, the lowest common multiple of 672,622,221,385,994 is 180361140960.

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.

672 x 622 x 221 x 385 x 994 = 35350783628160

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.

672 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 16, 21, 24, 28, 32, 42, 48, 56, 84, 96, 112, 168, 224, 336, 672

622 : 1, 2, 311, 622

221 : 1, 13, 17, 221

385 : 1, 5, 7, 11, 35, 55, 77, 385

994 : 1, 2, 7, 14, 71, 142, 497, 994

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 672,622,221,385,994, is 1.

Now, the common factors can be found like this.

672:2x 2x 2x 2x 2x 3x 7

622:2x 311

221:13x 17

385:5x 7x 11

994:2x 7x 71

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

2x 2x 7x 7 = 196

Therefore, the value for common factors is 196.

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 = 35350783628160/(1x196)

LCM = 35350783628160/196

LCM = 180361140960

Thus, we can understand that the LCM of 672,622,221,385,994 is 180361140960.
