HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 457, 274, 177 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 457, 274, 177 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 457, 274, 177 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 457, 274, 177 is 1.
HCF(457, 274, 177) = 1
HCF of 457, 274, 177 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 457, 274, 177 is 1.
Highest Common Factor of 457,274,177 is 1
Step 1: Since 457 > 274, we apply the division lemma to 457 and 274, to get
457 = 274 x 1 + 183
Step 2: Since the reminder 274 ≠ 0, we apply division lemma to 183 and 274, to get
274 = 183 x 1 + 91
Step 3: We consider the new divisor 183 and the new remainder 91, and apply the division lemma to get
183 = 91 x 2 + 1
We consider the new divisor 91 and the new remainder 1, and apply the division lemma to get
91 = 1 x 91 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 457 and 274 is 1
Notice that 1 = HCF(91,1) = HCF(183,91) = HCF(274,183) = HCF(457,274) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 177 > 1, we apply the division lemma to 177 and 1, to get
177 = 1 x 177 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 177 is 1
Notice that 1 = HCF(177,1) .
