HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 774, 989 i.e. 43 the largest integer that leaves a remainder zero for all numbers.
HCF of 774, 989 is 43 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 774, 989 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 774, 989 is 43.
HCF(774, 989) = 43
HCF of 774, 989 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 774, 989 is 43.
Highest Common Factor of 774,989 is 43
Step 1: Since 989 > 774, we apply the division lemma to 989 and 774, to get
989 = 774 x 1 + 215
Step 2: Since the reminder 774 ≠ 0, we apply division lemma to 215 and 774, to get
774 = 215 x 3 + 129
Step 3: We consider the new divisor 215 and the new remainder 129, and apply the division lemma to get
215 = 129 x 1 + 86
We consider the new divisor 129 and the new remainder 86,and apply the division lemma to get
129 = 86 x 1 + 43
We consider the new divisor 86 and the new remainder 43,and apply the division lemma to get
86 = 43 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 43, the HCF of 774 and 989 is 43
Notice that 43 = HCF(86,43) = HCF(129,86) = HCF(215,129) = HCF(774,215) = HCF(989,774) .
