HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 855, 25827 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 855, 25827 is 3 the largest number which exactly divides all the numbers i.e. where the remainder is zero. Let us get into the working of this example.
Consider we have numbers 855, 25827 and we need to find the HCF of these numbers. To do so, we need to choose the largest integer first and then as per Euclid's Division Lemma a = bq + r where 0 ≤ r ≤ b
Highest common factor (HCF) of 855, 25827 is 3.
HCF(855, 25827) = 3
HCF of 855, 25827 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 855, 25827 is 3.
Highest Common Factor of 855,25827 is 3
Step 1: Since 25827 > 855, we apply the division lemma to 25827 and 855, to get
25827 = 855 x 30 + 177
Step 2: Since the reminder 855 ≠ 0, we apply division lemma to 177 and 855, to get
855 = 177 x 4 + 147
Step 3: We consider the new divisor 177 and the new remainder 147, and apply the division lemma to get
177 = 147 x 1 + 30
We consider the new divisor 147 and the new remainder 30,and apply the division lemma to get
147 = 30 x 4 + 27
We consider the new divisor 30 and the new remainder 27,and apply the division lemma to get
30 = 27 x 1 + 3
We consider the new divisor 27 and the new remainder 3,and apply the division lemma to get
27 = 3 x 9 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 855 and 25827 is 3
Notice that 3 = HCF(27,3) = HCF(30,27) = HCF(147,30) = HCF(177,147) = HCF(855,177) = HCF(25827,855) .
