Given numbers are 746,494,931,690,172
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 746,494,931,690,172 is 267885623460.
Find LCM of 746,494,931,690,172 with Prime Factorization
| 2 | 746, 494, 931, 690, 172 |
| 19 | 373, 247, 931, 345, 86 |
| 373, 13, 49, 345, 86 |
Multiply the prime numbers at the bottom and the left side.
2 x 19 x 373 x 13 x 49 x 345 x 86 = 267885623460
Therefore, the lowest common multiple of 746,494,931,690,172 is 267885623460.
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.
746 x 494 x 931 x 690 x 172 = 40718614765920
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.
746 : 1, 2, 373, 746
494 : 1, 2, 13, 19, 26, 38, 247, 494
931 : 1, 7, 19, 49, 133, 931
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
172 : 1, 2, 4, 43, 86, 172
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 746,494,931,690,172, is 1.
Now, the common factors can be found like this.
746:2x 373
494:2x 13x 19
931:7x 7x 19
690:2x 3x 5x 23
172:2x 2x 43
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 19 = 152
Therefore, the value for common factors is 152.
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 = 40718614765920/(1x152)
LCM = 40718614765920/152
LCM = 267885623460
Thus, we can understand that the LCM of 746,494,931,690,172 is 267885623460.
