HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 277, 203, 943 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 277, 203, 943 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 277, 203, 943 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 277, 203, 943 is 1.

HCF(277, 203, 943) = 1

Highest common factor (HCF) of 277, 203, 943 is 1.

Highest Common Factor of 277,203,943 using Euclid's algorithm

Highest Common Factor of 277,203,943 is 1

Step 1: Since 277 > 203, we apply the division lemma to 277 and 203, to get

277 = 203 x 1 + 74

Step 2: Since the reminder 203 ≠ 0, we apply division lemma to 74 and 203, to get

203 = 74 x 2 + 55

Step 3: We consider the new divisor 74 and the new remainder 55, and apply the division lemma to get

74 = 55 x 1 + 19

We consider the new divisor 55 and the new remainder 19,and apply the division lemma to get

55 = 19 x 2 + 17

We consider the new divisor 19 and the new remainder 17,and apply the division lemma to get

19 = 17 x 1 + 2

We consider the new divisor 17 and the new remainder 2,and apply the division lemma to get

17 = 2 x 8 + 1

We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get

2 = 1 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 277 and 203 is 1

Notice that 1 = HCF(2,1) = HCF(17,2) = HCF(19,17) = HCF(55,19) = HCF(74,55) = HCF(203,74) = HCF(277,203) .

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

Step 1: Since 943 > 1, we apply the division lemma to 943 and 1, to get

943 = 1 x 943 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 943 is 1

Notice that 1 = HCF(943,1) .
