HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 798, 546 i.e. 42 the largest integer that leaves a remainder zero for all numbers.
HCF of 798, 546 is 42 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 798, 546 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 798, 546 is 42.
HCF(798, 546) = 42
HCF of 798, 546 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 798, 546 is 42.
Highest Common Factor of 798,546 is 42
Step 1: Since 798 > 546, we apply the division lemma to 798 and 546, to get
798 = 546 x 1 + 252
Step 2: Since the reminder 546 ≠ 0, we apply division lemma to 252 and 546, to get
546 = 252 x 2 + 42
Step 3: We consider the new divisor 252 and the new remainder 42, and apply the division lemma to get
252 = 42 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 42, the HCF of 798 and 546 is 42
Notice that 42 = HCF(252,42) = HCF(546,252) = HCF(798,546) .
