HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 345, 897 i.e. 69 the largest integer that leaves a remainder zero for all numbers.
HCF of 345, 897 is 69 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 345, 897 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 345, 897 is 69.
HCF(345, 897) = 69
HCF of 345, 897 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 345, 897 is 69.
Highest Common Factor of 345,897 is 69
Step 1: Since 897 > 345, we apply the division lemma to 897 and 345, to get
897 = 345 x 2 + 207
Step 2: Since the reminder 345 ≠ 0, we apply division lemma to 207 and 345, to get
345 = 207 x 1 + 138
Step 3: We consider the new divisor 207 and the new remainder 138, and apply the division lemma to get
207 = 138 x 1 + 69
We consider the new divisor 138 and the new remainder 69, and apply the division lemma to get
138 = 69 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 69, the HCF of 345 and 897 is 69
Notice that 69 = HCF(138,69) = HCF(207,138) = HCF(345,207) = HCF(897,345) .
