HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 273, 921 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 273, 921 is 3 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 273, 921 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 273, 921 is 3.
HCF(273, 921) = 3
HCF of 273, 921 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 273, 921 is 3.
Highest Common Factor of 273,921 is 3
Step 1: Since 921 > 273, we apply the division lemma to 921 and 273, to get
921 = 273 x 3 + 102
Step 2: Since the reminder 273 ≠ 0, we apply division lemma to 102 and 273, to get
273 = 102 x 2 + 69
Step 3: We consider the new divisor 102 and the new remainder 69, and apply the division lemma to get
102 = 69 x 1 + 33
We consider the new divisor 69 and the new remainder 33,and apply the division lemma to get
69 = 33 x 2 + 3
We consider the new divisor 33 and the new remainder 3,and apply the division lemma to get
33 = 3 x 11 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 273 and 921 is 3
Notice that 3 = HCF(33,3) = HCF(69,33) = HCF(102,69) = HCF(273,102) = HCF(921,273) .
