HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 671, 492 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 671, 492 is 1 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 671, 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 671, 492 is 1.
HCF(671, 492) = 1
HCF of 671, 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 671, 492 is 1.
Highest Common Factor of 671,492 is 1
Step 1: Since 671 > 492, we apply the division lemma to 671 and 492, to get
671 = 492 x 1 + 179
Step 2: Since the reminder 492 ≠ 0, we apply division lemma to 179 and 492, to get
492 = 179 x 2 + 134
Step 3: We consider the new divisor 179 and the new remainder 134, and apply the division lemma to get
179 = 134 x 1 + 45
We consider the new divisor 134 and the new remainder 45,and apply the division lemma to get
134 = 45 x 2 + 44
We consider the new divisor 45 and the new remainder 44,and apply the division lemma to get
45 = 44 x 1 + 1
We consider the new divisor 44 and the new remainder 1,and apply the division lemma to get
44 = 1 x 44 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 671 and 492 is 1
Notice that 1 = HCF(44,1) = HCF(45,44) = HCF(134,45) = HCF(179,134) = HCF(492,179) = HCF(671,492) .
