HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 956, 4020 i.e. 4 the largest integer that leaves a remainder zero for all numbers.
HCF of 956, 4020 is 4 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 956, 4020 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 956, 4020 is 4.
HCF(956, 4020) = 4
HCF of 956, 4020 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 956, 4020 is 4.
Highest Common Factor of 956,4020 is 4
Step 1: Since 4020 > 956, we apply the division lemma to 4020 and 956, to get
4020 = 956 x 4 + 196
Step 2: Since the reminder 956 ≠ 0, we apply division lemma to 196 and 956, to get
956 = 196 x 4 + 172
Step 3: We consider the new divisor 196 and the new remainder 172, and apply the division lemma to get
196 = 172 x 1 + 24
We consider the new divisor 172 and the new remainder 24,and apply the division lemma to get
172 = 24 x 7 + 4
We consider the new divisor 24 and the new remainder 4,and apply the division lemma to get
24 = 4 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 956 and 4020 is 4
Notice that 4 = HCF(24,4) = HCF(172,24) = HCF(196,172) = HCF(956,196) = HCF(4020,956) .
