HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 962, 78790 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 962, 78790 is 2 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 962, 78790 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 962, 78790 is 2.
HCF(962, 78790) = 2
HCF of 962, 78790 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 962, 78790 is 2.
Highest Common Factor of 962,78790 is 2
Step 1: Since 78790 > 962, we apply the division lemma to 78790 and 962, to get
78790 = 962 x 81 + 868
Step 2: Since the reminder 962 ≠ 0, we apply division lemma to 868 and 962, to get
962 = 868 x 1 + 94
Step 3: We consider the new divisor 868 and the new remainder 94, and apply the division lemma to get
868 = 94 x 9 + 22
We consider the new divisor 94 and the new remainder 22,and apply the division lemma to get
94 = 22 x 4 + 6
We consider the new divisor 22 and the new remainder 6,and apply the division lemma to get
22 = 6 x 3 + 4
We consider the new divisor 6 and the new remainder 4,and apply the division lemma to get
6 = 4 x 1 + 2
We consider the new divisor 4 and the new remainder 2,and apply the division lemma to get
4 = 2 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 962 and 78790 is 2
Notice that 2 = HCF(4,2) = HCF(6,4) = HCF(22,6) = HCF(94,22) = HCF(868,94) = HCF(962,868) = HCF(78790,962) .
