HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 388, 166, 227, 891 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 388, 166, 227, 891 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 388, 166, 227, 891 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 388, 166, 227, 891 is 1.
HCF(388, 166, 227, 891) = 1
HCF of 388, 166, 227, 891 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 388, 166, 227, 891 is 1.
Highest Common Factor of 388,166,227,891 is 1
Step 1: Since 388 > 166, we apply the division lemma to 388 and 166, to get
388 = 166 x 2 + 56
Step 2: Since the reminder 166 ≠ 0, we apply division lemma to 56 and 166, to get
166 = 56 x 2 + 54
Step 3: We consider the new divisor 56 and the new remainder 54, and apply the division lemma to get
56 = 54 x 1 + 2
We consider the new divisor 54 and the new remainder 2, and apply the division lemma to get
54 = 2 x 27 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 388 and 166 is 2
Notice that 2 = HCF(54,2) = HCF(56,54) = HCF(166,56) = HCF(388,166) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 227 > 2, we apply the division lemma to 227 and 2, to get
227 = 2 x 113 + 1
Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 2 and 227 is 1
Notice that 1 = HCF(2,1) = HCF(227,2) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 891 > 1, we apply the division lemma to 891 and 1, to get
891 = 1 x 891 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 891 is 1
Notice that 1 = HCF(891,1) .
