HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 966, 621 i.e. 69 the largest integer that leaves a remainder zero for all numbers.
HCF of 966, 621 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 966, 621 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 966, 621 is 69.
HCF(966, 621) = 69
HCF of 966, 621 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 966, 621 is 69.
Highest Common Factor of 966,621 is 69
Step 1: Since 966 > 621, we apply the division lemma to 966 and 621, to get
966 = 621 x 1 + 345
Step 2: Since the reminder 621 ≠ 0, we apply division lemma to 345 and 621, to get
621 = 345 x 1 + 276
Step 3: We consider the new divisor 345 and the new remainder 276, and apply the division lemma to get
345 = 276 x 1 + 69
We consider the new divisor 276 and the new remainder 69, and apply the division lemma to get
276 = 69 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 69, the HCF of 966 and 621 is 69
Notice that 69 = HCF(276,69) = HCF(345,276) = HCF(621,345) = HCF(966,621) .
