HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 961, 243, 673 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 961, 243, 673 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 961, 243, 673 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 961, 243, 673 is 1.

HCF(961, 243, 673) = 1

HCF of 961, 243, 673 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 961, 243, 673 is 1.

Highest Common Factor of 961,243,673 using Euclid's algorithm

Highest Common Factor of 961,243,673 is 1

Step 1: Since 961 > 243, we apply the division lemma to 961 and 243, to get

961 = 243 x 3 + 232

Step 2: Since the reminder 243 ≠ 0, we apply division lemma to 232 and 243, to get

243 = 232 x 1 + 11

Step 3: We consider the new divisor 232 and the new remainder 11, and apply the division lemma to get

232 = 11 x 21 + 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 961 and 243 is 1

Notice that 1 = HCF(11,1) = HCF(232,11) = HCF(243,232) = HCF(961,243) .


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

Step 1: Since 673 > 1, we apply the division lemma to 673 and 1, to get

673 = 1 x 673 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 673 is 1

Notice that 1 = HCF(673,1) .
