Given numbers are 781,319,678,675,796
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 781,319,678,675,796 is 1375131770100.
Find LCM of 781,319,678,675,796 with Prime Factorization
2 | 781, 319, 678, 675, 796 |
3 | 781, 319, 339, 675, 398 |
11 | 781, 319, 113, 225, 398 |
71, 29, 113, 225, 398 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 71 x 29 x 113 x 225 x 398 = 1375131770100
Therefore, the lowest common multiple of 781,319,678,675,796 is 1375131770100.
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 319 x 678 x 675 x 796 = 90758696826600
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
319 : 1, 11, 29, 319
678 : 1, 2, 3, 6, 113, 226, 339, 678
675 : 1, 3, 5, 9, 15, 25, 27, 45, 75, 135, 225, 675
796 : 1, 2, 4, 199, 398, 796
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 781,319,678,675,796, is 1.
Now, the common factors can be found like this.
781:11x 71
319:11x 29
678:2x 3x 113
675:3x 3x 3x 5x 5
796:2x 2x 199
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 11 = 66
Therefore, the value for common factors is 66.
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 = 90758696826600/(1x66)
LCM = 90758696826600/66
LCM = 1375131770100
Thus, we can understand that the LCM of 781,319,678,675,796 is 1375131770100.
