Given numbers are 684,777,620,902,438

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

The LCM of 684,777,620,902,438 is 904038583140.

Find LCM of 684,777,620,902,438 with Prime Factorization

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

2 x 2 x 3 x 57 x 259 x 155 x 451 x 73 = 904038583140

Therefore, the lowest common multiple of 684,777,620,902,438 is 904038583140.

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.

684 x 777 x 620 x 902 x 438 = 130181555972160

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.

684 : 1, 2, 3, 4, 6, 9, 12, 18, 19, 36, 38, 57, 76, 114, 171, 228, 342, 684

777 : 1, 3, 7, 21, 37, 111, 259, 777

620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620

902 : 1, 2, 11, 22, 41, 82, 451, 902

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 684,777,620,902,438, is 1.

Now, the common factors can be found like this.

684:2x 2x 3x 3x 19

777:3x 7x 37

620:2x 2x 5x 31

902:2x 11x 41

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 2x 2x 2x 3x 3 = 144

Therefore, the value for common factors is 144.

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 = 130181555972160/(1x144)

LCM = 130181555972160/144

LCM = 904038583140

Thus, we can understand that the LCM of 684,777,620,902,438 is 904038583140.
