Given numbers are 731,697,943,577
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 731,697,943,577 is 397745141.
Find LCM of 731,697,943,577 with Prime Factorization
| 17 | 731, 697, 943, 577 |
| 41 | 43, 41, 943, 577 |
| 43, 1, 23, 577 |
Multiply the prime numbers at the bottom and the left side.
17 x 41 x 43 x 1 x 23 x 577 = 397745141
Therefore, the lowest common multiple of 731,697,943,577 is 397745141.
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.
731 x 697 x 943 x 577 = 277228363277
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.
731 : 1, 17, 43, 731
697 : 1, 17, 41, 697
943 : 1, 23, 41, 943
577 : 1, 577
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 731,697,943,577, is 1.
Now, the common factors can be found like this.
731:17x 43
697:17x 41
943:23x 41
577:577
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
17x 41 = 697
Therefore, the value for common factors is 697.
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 = 277228363277/(1x697)
LCM = 277228363277/697
LCM = 397745141
Thus, we can understand that the LCM of 731,697,943,577 is 397745141.
