Given numbers are 777,321,533,943
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 777,321,533,943 is 1019201001.
Find LCM of 777,321,533,943 with Prime Factorization
| 3 | 777, 321, 533, 943 |
| 41 | 259, 107, 533, 943 |
| 259, 107, 13, 23 |
Multiply the prime numbers at the bottom and the left side.
3 x 41 x 259 x 107 x 13 x 23 = 1019201001
Therefore, the lowest common multiple of 777,321,533,943 is 1019201001.
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.
777 x 321 x 533 x 943 = 125361723123
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.
777 : 1, 3, 7, 21, 37, 111, 259, 777
321 : 1, 3, 107, 321
533 : 1, 13, 41, 533
943 : 1, 23, 41, 943
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 777,321,533,943, is 1.
Now, the common factors can be found like this.
777:3x 7x 37
321:3x 107
533:13x 41
943:23x 41
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 41 = 123
Therefore, the value for common factors is 123.
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 = 125361723123/(1x123)
LCM = 125361723123/123
LCM = 1019201001
Thus, we can understand that the LCM of 777,321,533,943 is 1019201001.
