Given numbers are 903,721,759,923

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

The LCM of 903,721,759,923 is 21719368671.

Find LCM of 903,721,759,923 with Prime Factorization


3 903, 721, 759, 923
7 301, 721, 253, 923
43, 103, 253, 923

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

3 x 7 x 43 x 103 x 253 x 923 = 21719368671

Therefore, the lowest common multiple of 903,721,759,923 is 21719368671.

LCM Formula to Find Lowest Common Multiple of 903,721,759,923

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.

903 x 721 x 759 x 923 = 456106742091

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.

903 : 1, 3, 7, 21, 43, 129, 301, 903

721 : 1, 7, 103, 721

759 : 1, 3, 11, 23, 33, 69, 253, 759

923 : 1, 13, 71, 923

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 903,721,759,923, is 1.

Now, the common factors can be found like this.

903:3x 7x 43

721:7x 103

759:3x 11x 23

923:13x 71

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

3x 7 = 21

Therefore, the value for common factors is 21.

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 = 456106742091/(1x21)

LCM = 456106742091/21

LCM = 21719368671

Thus, we can understand that the LCM of 903,721,759,923 is 21719368671.
