HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 227, 644 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 227, 644 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 227, 644 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 227, 644 is 1.
HCF(227, 644) = 1
HCF of 227, 644 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 227, 644 is 1.
Highest Common Factor of 227,644 is 1
Step 1: Since 644 > 227, we apply the division lemma to 644 and 227, to get
644 = 227 x 2 + 190
Step 2: Since the reminder 227 ≠ 0, we apply division lemma to 190 and 227, to get
227 = 190 x 1 + 37
Step 3: We consider the new divisor 190 and the new remainder 37, and apply the division lemma to get
190 = 37 x 5 + 5
We consider the new divisor 37 and the new remainder 5,and apply the division lemma to get
37 = 5 x 7 + 2
We consider the new divisor 5 and the new remainder 2,and apply the division lemma to get
5 = 2 x 2 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma 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 227 and 644 is 1
Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(37,5) = HCF(190,37) = HCF(227,190) = HCF(644,227) .
