Given numbers are 781,340,648,967,892
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 781,340,648,967,892 is 9276332404680.
Find LCM of 781,340,648,967,892 with Prime Factorization
| 2 | 781, 340, 648, 967, 892 |
| 2 | 781, 170, 324, 967, 446 |
| 781, 85, 162, 967, 223 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 781 x 85 x 162 x 967 x 223 = 9276332404680
Therefore, the lowest common multiple of 781,340,648,967,892 is 9276332404680.
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.
781 x 340 x 648 x 967 x 892 = 148421318474880
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.
781 : 1, 11, 71, 781
340 : 1, 2, 4, 5, 10, 17, 20, 34, 68, 85, 170, 340
648 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 81, 108, 162, 216, 324, 648
967 : 1, 967
892 : 1, 2, 4, 223, 446, 892
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 781,340,648,967,892, is 1.
Now, the common factors can be found like this.
781:11x 71
340:2x 2x 5x 17
648:2x 2x 2x 3x 3x 3x 3
967:967
892:2x 2x 223
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 2 = 16
Therefore, the value for common factors is 16.
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 = 148421318474880/(1x16)
LCM = 148421318474880/16
LCM = 9276332404680
Thus, we can understand that the LCM of 781,340,648,967,892 is 9276332404680.
