HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 727, 949 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 727, 949 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 727, 949 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 727, 949 is 1.

HCF(727, 949) = 1

Highest common factor (HCF) of 727, 949 is 1.

Highest Common Factor of 727,949 using Euclid's algorithm

Highest Common Factor of 727,949 is 1

Step 1: Since 949 > 727, we apply the division lemma to 949 and 727, to get

949 = 727 x 1 + 222

Step 2: Since the reminder 727 ≠ 0, we apply division lemma to 222 and 727, to get

727 = 222 x 3 + 61

Step 3: We consider the new divisor 222 and the new remainder 61, and apply the division lemma to get

222 = 61 x 3 + 39

We consider the new divisor 61 and the new remainder 39,and apply the division lemma to get

61 = 39 x 1 + 22

We consider the new divisor 39 and the new remainder 22,and apply the division lemma to get

39 = 22 x 1 + 17

We consider the new divisor 22 and the new remainder 17,and apply the division lemma to get

22 = 17 x 1 + 5

We consider the new divisor 17 and the new remainder 5,and apply the division lemma to get

17 = 5 x 3 + 2

We consider the new divisor 5 and the new remainder 2,and apply the division lemma to get

5 = 2 x 2 + 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 727 and 949 is 1

Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(17,5) = HCF(22,17) = HCF(39,22) = HCF(61,39) = HCF(222,61) = HCF(727,222) = HCF(949,727) .
