HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 494, 91 i.e. 13 the largest integer that leaves a remainder zero for all numbers.
HCF of 494, 91 is 13 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 494, 91 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 494, 91 is 13.
HCF(494, 91) = 13
HCF of 494, 91 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 494, 91 is 13.
Highest Common Factor of 494,91 is 13
Step 1: Since 494 > 91, we apply the division lemma to 494 and 91, to get
494 = 91 x 5 + 39
Step 2: Since the reminder 91 ≠ 0, we apply division lemma to 39 and 91, to get
91 = 39 x 2 + 13
Step 3: We consider the new divisor 39 and the new remainder 13, and apply the division lemma to get
39 = 13 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 13, the HCF of 494 and 91 is 13
Notice that 13 = HCF(39,13) = HCF(91,39) = HCF(494,91) .
