HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 855, 822 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 855, 822 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, 822 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, 822 is 3.
HCF(855, 822) = 3
HCF of 855, 822 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, 822 is 3.
Highest Common Factor of 855,822 is 3
Step 1: Since 855 > 822, we apply the division lemma to 855 and 822, to get
855 = 822 x 1 + 33
Step 2: Since the reminder 822 ≠ 0, we apply division lemma to 33 and 822, to get
822 = 33 x 24 + 30
Step 3: We consider the new divisor 33 and the new remainder 30, and apply the division lemma to get
33 = 30 x 1 + 3
We consider the new divisor 30 and the new remainder 3, and apply the division lemma to get
30 = 3 x 10 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 855 and 822 is 3
Notice that 3 = HCF(30,3) = HCF(33,30) = HCF(822,33) = HCF(855,822) .
