HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 622, 242 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 622, 242 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 622, 242 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 622, 242 is 2.
HCF(622, 242) = 2
HCF of 622, 242 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 622, 242 is 2.
Highest Common Factor of 622,242 is 2
Step 1: Since 622 > 242, we apply the division lemma to 622 and 242, to get
622 = 242 x 2 + 138
Step 2: Since the reminder 242 ≠ 0, we apply division lemma to 138 and 242, to get
242 = 138 x 1 + 104
Step 3: We consider the new divisor 138 and the new remainder 104, and apply the division lemma to get
138 = 104 x 1 + 34
We consider the new divisor 104 and the new remainder 34,and apply the division lemma to get
104 = 34 x 3 + 2
We consider the new divisor 34 and the new remainder 2,and apply the division lemma to get
34 = 2 x 17 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 622 and 242 is 2
Notice that 2 = HCF(34,2) = HCF(104,34) = HCF(138,104) = HCF(242,138) = HCF(622,242) .
