HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 958, 3981 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 958, 3981 is 1 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 958, 3981 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 958, 3981 is 1.
HCF(958, 3981) = 1
HCF of 958, 3981 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 958, 3981 is 1.
Highest Common Factor of 958,3981 is 1
Step 1: Since 3981 > 958, we apply the division lemma to 3981 and 958, to get
3981 = 958 x 4 + 149
Step 2: Since the reminder 958 ≠ 0, we apply division lemma to 149 and 958, to get
958 = 149 x 6 + 64
Step 3: We consider the new divisor 149 and the new remainder 64, and apply the division lemma to get
149 = 64 x 2 + 21
We consider the new divisor 64 and the new remainder 21,and apply the division lemma to get
64 = 21 x 3 + 1
We consider the new divisor 21 and the new remainder 1,and apply the division lemma to get
21 = 1 x 21 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 958 and 3981 is 1
Notice that 1 = HCF(21,1) = HCF(64,21) = HCF(149,64) = HCF(958,149) = HCF(3981,958) .
