HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 373, 171, 977 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 373, 171, 977 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 373, 171, 977 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 373, 171, 977 is 1.
HCF(373, 171, 977) = 1
HCF of 373, 171, 977 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 373, 171, 977 is 1.
Highest Common Factor of 373,171,977 is 1
Step 1: Since 373 > 171, we apply the division lemma to 373 and 171, to get
373 = 171 x 2 + 31
Step 2: Since the reminder 171 ≠ 0, we apply division lemma to 31 and 171, to get
171 = 31 x 5 + 16
Step 3: We consider the new divisor 31 and the new remainder 16, and apply the division lemma to get
31 = 16 x 1 + 15
We consider the new divisor 16 and the new remainder 15,and apply the division lemma to get
16 = 15 x 1 + 1
We consider the new divisor 15 and the new remainder 1,and apply the division lemma to get
15 = 1 x 15 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 373 and 171 is 1
Notice that 1 = HCF(15,1) = HCF(16,15) = HCF(31,16) = HCF(171,31) = HCF(373,171) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 977 > 1, we apply the division lemma to 977 and 1, to get
977 = 1 x 977 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 977 is 1
Notice that 1 = HCF(977,1) .
