HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 746, 987, 173 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 746, 987, 173 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 746, 987, 173 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 746, 987, 173 is 1.

HCF(746, 987, 173) = 1

HCF of 746, 987, 173 using Euclid's algorithm

Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.

HCF of:

Highest common factor (HCF) of 746, 987, 173 is 1.

Highest Common Factor of 746,987,173 using Euclid's algorithm

Highest Common Factor of 746,987,173 is 1

Step 1: Since 987 > 746, we apply the division lemma to 987 and 746, to get

987 = 746 x 1 + 241

Step 2: Since the reminder 746 ≠ 0, we apply division lemma to 241 and 746, to get

746 = 241 x 3 + 23

Step 3: We consider the new divisor 241 and the new remainder 23, and apply the division lemma to get

241 = 23 x 10 + 11

We consider the new divisor 23 and the new remainder 11,and apply the division lemma to get

23 = 11 x 2 + 1

We consider the new divisor 11 and the new remainder 1,and apply the division lemma to get

11 = 1 x 11 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 746 and 987 is 1

Notice that 1 = HCF(11,1) = HCF(23,11) = HCF(241,23) = HCF(746,241) = HCF(987,746) .


We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma

Step 1: Since 173 > 1, we apply the division lemma to 173 and 1, to get

173 = 1 x 173 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 173 is 1

Notice that 1 = HCF(173,1) .
