HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 188, 923, 365, 81 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 188, 923, 365, 81 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 188, 923, 365, 81 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 188, 923, 365, 81 is 1.
HCF(188, 923, 365, 81) = 1
HCF of 188, 923, 365, 81 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 188, 923, 365, 81 is 1.
Highest Common Factor of 188,923,365,81 is 1
Step 1: Since 923 > 188, we apply the division lemma to 923 and 188, to get
923 = 188 x 4 + 171
Step 2: Since the reminder 188 ≠ 0, we apply division lemma to 171 and 188, to get
188 = 171 x 1 + 17
Step 3: We consider the new divisor 171 and the new remainder 17, and apply the division lemma to get
171 = 17 x 10 + 1
We consider the new divisor 17 and the new remainder 1, and apply the division lemma to get
17 = 1 x 17 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 188 and 923 is 1
Notice that 1 = HCF(17,1) = HCF(171,17) = HCF(188,171) = HCF(923,188) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 365 > 1, we apply the division lemma to 365 and 1, to get
365 = 1 x 365 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 365 is 1
Notice that 1 = HCF(365,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 81 > 1, we apply the division lemma to 81 and 1, to get
81 = 1 x 81 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 81 is 1
Notice that 1 = HCF(81,1) .
