HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 17, 85, 55, 373 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 17, 85, 55, 373 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 17, 85, 55, 373 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 17, 85, 55, 373 is 1.
HCF(17, 85, 55, 373) = 1
HCF of 17, 85, 55, 373 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 17, 85, 55, 373 is 1.
Highest Common Factor of 17,85,55,373 is 1
Step 1: Since 85 > 17, we apply the division lemma to 85 and 17, to get
85 = 17 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 17, the HCF of 17 and 85 is 17
Notice that 17 = HCF(85,17) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 55 > 17, we apply the division lemma to 55 and 17, to get
55 = 17 x 3 + 4
Step 2: Since the reminder 17 ≠ 0, we apply division lemma to 4 and 17, to get
17 = 4 x 4 + 1
Step 3: We consider the new divisor 4 and the new remainder 1, and apply the division lemma to get
4 = 1 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 17 and 55 is 1
Notice that 1 = HCF(4,1) = HCF(17,4) = HCF(55,17) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 373 > 1, we apply the division lemma to 373 and 1, to get
373 = 1 x 373 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 373 is 1
Notice that 1 = HCF(373,1) .
