Given numbers are 481,620,386,242,765
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 481,620,386,242,765 is 1065542743980.
Find LCM of 481,620,386,242,765 with Prime Factorization
2 | 481, 620, 386, 242, 765 |
5 | 481, 310, 193, 121, 765 |
481, 62, 193, 121, 153 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 481 x 62 x 193 x 121 x 153 = 1065542743980
Therefore, the lowest common multiple of 481,620,386,242,765 is 1065542743980.
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.
481 x 620 x 386 x 242 x 765 = 21310854879600
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.
481 : 1, 13, 37, 481
620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620
386 : 1, 2, 193, 386
242 : 1, 2, 11, 22, 121, 242
765 : 1, 3, 5, 9, 15, 17, 45, 51, 85, 153, 255, 765
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 481,620,386,242,765, is 1.
Now, the common factors can be found like this.
481:13x 37
620:2x 2x 5x 31
386:2x 193
242:2x 11x 11
765:3x 3x 5x 17
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 5 = 20
Therefore, the value for common factors is 20.
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 = 21310854879600/(1x20)
LCM = 21310854879600/20
LCM = 1065542743980
Thus, we can understand that the LCM of 481,620,386,242,765 is 1065542743980.
