HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 552, 161 i.e. 23 the largest integer that leaves a remainder zero for all numbers.
HCF of 552, 161 is 23 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 552, 161 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 552, 161 is 23.
HCF(552, 161) = 23
HCF of 552, 161 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 552, 161 is 23.
Highest Common Factor of 552,161 is 23
Step 1: Since 552 > 161, we apply the division lemma to 552 and 161, to get
552 = 161 x 3 + 69
Step 2: Since the reminder 161 ≠ 0, we apply division lemma to 69 and 161, to get
161 = 69 x 2 + 23
Step 3: We consider the new divisor 69 and the new remainder 23, and apply the division lemma to get
69 = 23 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 23, the HCF of 552 and 161 is 23
Notice that 23 = HCF(69,23) = HCF(161,69) = HCF(552,161) .
