HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 742, 474, 66 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 742, 474, 66 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 742, 474, 66 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 742, 474, 66 is 2.
HCF(742, 474, 66) = 2
HCF of 742, 474, 66 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 742, 474, 66 is 2.
Highest Common Factor of 742,474,66 is 2
Step 1: Since 742 > 474, we apply the division lemma to 742 and 474, to get
742 = 474 x 1 + 268
Step 2: Since the reminder 474 ≠ 0, we apply division lemma to 268 and 474, to get
474 = 268 x 1 + 206
Step 3: We consider the new divisor 268 and the new remainder 206, and apply the division lemma to get
268 = 206 x 1 + 62
We consider the new divisor 206 and the new remainder 62,and apply the division lemma to get
206 = 62 x 3 + 20
We consider the new divisor 62 and the new remainder 20,and apply the division lemma to get
62 = 20 x 3 + 2
We consider the new divisor 20 and the new remainder 2,and apply the division lemma to get
20 = 2 x 10 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 742 and 474 is 2
Notice that 2 = HCF(20,2) = HCF(62,20) = HCF(206,62) = HCF(268,206) = HCF(474,268) = HCF(742,474) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 66 > 2, we apply the division lemma to 66 and 2, to get
66 = 2 x 33 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 66 is 2
Notice that 2 = HCF(66,2) .
