HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 254, 822 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 254, 822 is 2 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 254, 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 254, 822 is 2.
HCF(254, 822) = 2
HCF of 254, 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 254, 822 is 2.
Highest Common Factor of 254,822 is 2
Step 1: Since 822 > 254, we apply the division lemma to 822 and 254, to get
822 = 254 x 3 + 60
Step 2: Since the reminder 254 ≠ 0, we apply division lemma to 60 and 254, to get
254 = 60 x 4 + 14
Step 3: We consider the new divisor 60 and the new remainder 14, and apply the division lemma to get
60 = 14 x 4 + 4
We consider the new divisor 14 and the new remainder 4,and apply the division lemma to get
14 = 4 x 3 + 2
We consider the new divisor 4 and the new remainder 2,and apply the division lemma to get
4 = 2 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 254 and 822 is 2
Notice that 2 = HCF(4,2) = HCF(14,4) = HCF(60,14) = HCF(254,60) = HCF(822,254) .
