HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 549, 427 i.e. 61 the largest integer that leaves a remainder zero for all numbers.
HCF of 549, 427 is 61 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 549, 427 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 549, 427 is 61.
HCF(549, 427) = 61
HCF of 549, 427 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 549, 427 is 61.
Highest Common Factor of 549,427 is 61
Step 1: Since 549 > 427, we apply the division lemma to 549 and 427, to get
549 = 427 x 1 + 122
Step 2: Since the reminder 427 ≠ 0, we apply division lemma to 122 and 427, to get
427 = 122 x 3 + 61
Step 3: We consider the new divisor 122 and the new remainder 61, and apply the division lemma to get
122 = 61 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 61, the HCF of 549 and 427 is 61
Notice that 61 = HCF(122,61) = HCF(427,122) = HCF(549,427) .
