HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 462, 746 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 462, 746 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 462, 746 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 462, 746 is 2.
HCF(462, 746) = 2
HCF of 462, 746 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 462, 746 is 2.
Highest Common Factor of 462,746 is 2
Step 1: Since 746 > 462, we apply the division lemma to 746 and 462, to get
746 = 462 x 1 + 284
Step 2: Since the reminder 462 ≠ 0, we apply division lemma to 284 and 462, to get
462 = 284 x 1 + 178
Step 3: We consider the new divisor 284 and the new remainder 178, and apply the division lemma to get
284 = 178 x 1 + 106
We consider the new divisor 178 and the new remainder 106,and apply the division lemma to get
178 = 106 x 1 + 72
We consider the new divisor 106 and the new remainder 72,and apply the division lemma to get
106 = 72 x 1 + 34
We consider the new divisor 72 and the new remainder 34,and apply the division lemma to get
72 = 34 x 2 + 4
We consider the new divisor 34 and the new remainder 4,and apply the division lemma to get
34 = 4 x 8 + 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 462 and 746 is 2
Notice that 2 = HCF(4,2) = HCF(34,4) = HCF(72,34) = HCF(106,72) = HCF(178,106) = HCF(284,178) = HCF(462,284) = HCF(746,462) .
