HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 273, 946, 689 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 273, 946, 689 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 273, 946, 689 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 273, 946, 689 is 1.

HCF(273, 946, 689) = 1

HCF of 273, 946, 689 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 273, 946, 689 is 1.

Highest Common Factor of 273,946,689 using Euclid's algorithm

Highest Common Factor of 273,946,689 is 1

Step 1: Since 946 > 273, we apply the division lemma to 946 and 273, to get

946 = 273 x 3 + 127

Step 2: Since the reminder 273 ≠ 0, we apply division lemma to 127 and 273, to get

273 = 127 x 2 + 19

Step 3: We consider the new divisor 127 and the new remainder 19, and apply the division lemma to get

127 = 19 x 6 + 13

We consider the new divisor 19 and the new remainder 13,and apply the division lemma to get

19 = 13 x 1 + 6

We consider the new divisor 13 and the new remainder 6,and apply the division lemma to get

13 = 6 x 2 + 1

We consider the new divisor 6 and the new remainder 1,and apply the division lemma to get

6 = 1 x 6 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 273 and 946 is 1

Notice that 1 = HCF(6,1) = HCF(13,6) = HCF(19,13) = HCF(127,19) = HCF(273,127) = HCF(946,273) .

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

Step 1: Since 689 > 1, we apply the division lemma to 689 and 1, to get

689 = 1 x 689 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 689 is 1

Notice that 1 = HCF(689,1) .
