Given numbers are 777,740,402,461
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 777,740,402,461 is 479983980.
Find LCM of 777,740,402,461 with Prime Factorization
| 2 | 777, 740, 402, 461 |
| 3 | 777, 370, 201, 461 |
| 37 | 259, 370, 67, 461 |
| 7, 10, 67, 461 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 37 x 7 x 10 x 67 x 461 = 479983980
Therefore, the lowest common multiple of 777,740,402,461 is 479983980.
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 740 x 402 x 461 = 106556443560
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
740 : 1, 2, 4, 5, 10, 20, 37, 74, 148, 185, 370, 740
402 : 1, 2, 3, 6, 67, 134, 201, 402
461 : 1, 461
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 777,740,402,461, is 1.
Now, the common factors can be found like this.
777:3x 7x 37
740:2x 2x 5x 37
402:2x 3x 67
461:461
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 37 = 222
Therefore, the value for common factors is 222.
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 = 106556443560/(1x222)
LCM = 106556443560/222
LCM = 479983980
Thus, we can understand that the LCM of 777,740,402,461 is 479983980.
