HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 424, 268 i.e. 4 the largest integer that leaves a remainder zero for all numbers.
HCF of 424, 268 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 424, 268 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 424, 268 is 4.
HCF(424, 268) = 4
HCF of 424, 268 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 424, 268 is 4.
Highest Common Factor of 424,268 is 4
Step 1: Since 424 > 268, we apply the division lemma to 424 and 268, to get
424 = 268 x 1 + 156
Step 2: Since the reminder 268 ≠ 0, we apply division lemma to 156 and 268, to get
268 = 156 x 1 + 112
Step 3: We consider the new divisor 156 and the new remainder 112, and apply the division lemma to get
156 = 112 x 1 + 44
We consider the new divisor 112 and the new remainder 44,and apply the division lemma to get
112 = 44 x 2 + 24
We consider the new divisor 44 and the new remainder 24,and apply the division lemma to get
44 = 24 x 1 + 20
We consider the new divisor 24 and the new remainder 20,and apply the division lemma to get
24 = 20 x 1 + 4
We consider the new divisor 20 and the new remainder 4,and apply the division lemma to get
20 = 4 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 424 and 268 is 4
Notice that 4 = HCF(20,4) = HCF(24,20) = HCF(44,24) = HCF(112,44) = HCF(156,112) = HCF(268,156) = HCF(424,268) .
