HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 963, 79428 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 963, 79428 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 963, 79428 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 963, 79428 is 3.
HCF(963, 79428) = 3
HCF of 963, 79428 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 963, 79428 is 3.
Highest Common Factor of 963,79428 is 3
Step 1: Since 79428 > 963, we apply the division lemma to 79428 and 963, to get
79428 = 963 x 82 + 462
Step 2: Since the reminder 963 ≠ 0, we apply division lemma to 462 and 963, to get
963 = 462 x 2 + 39
Step 3: We consider the new divisor 462 and the new remainder 39, and apply the division lemma to get
462 = 39 x 11 + 33
We consider the new divisor 39 and the new remainder 33,and apply the division lemma to get
39 = 33 x 1 + 6
We consider the new divisor 33 and the new remainder 6,and apply the division lemma to get
33 = 6 x 5 + 3
We consider the new divisor 6 and the new remainder 3,and apply the division lemma to get
6 = 3 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 963 and 79428 is 3
Notice that 3 = HCF(6,3) = HCF(33,6) = HCF(39,33) = HCF(462,39) = HCF(963,462) = HCF(79428,963) .
