HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 51, 492 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 51, 492 is 3 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 51, 492 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 51, 492 is 3.
HCF(51, 492) = 3
HCF of 51, 492 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 51, 492 is 3.
Highest Common Factor of 51,492 is 3
Step 1: Since 492 > 51, we apply the division lemma to 492 and 51, to get
492 = 51 x 9 + 33
Step 2: Since the reminder 51 ≠ 0, we apply division lemma to 33 and 51, to get
51 = 33 x 1 + 18
Step 3: We consider the new divisor 33 and the new remainder 18, and apply the division lemma to get
33 = 18 x 1 + 15
We consider the new divisor 18 and the new remainder 15,and apply the division lemma to get
18 = 15 x 1 + 3
We consider the new divisor 15 and the new remainder 3,and apply the division lemma to get
15 = 3 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 51 and 492 is 3
Notice that 3 = HCF(15,3) = HCF(18,15) = HCF(33,18) = HCF(51,33) = HCF(492,51) .
