HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 277, 705, 647 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 277, 705, 647 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, 705, 647 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, 705, 647 is 1.

HCF(277, 705, 647) = 1

HCF of 277, 705, 647 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 277, 705, 647 is 1.

Highest Common Factor of 277,705,647 using Euclid's algorithm

Highest Common Factor of 277,705,647 is 1

Step 1: Since 705 > 277, we apply the division lemma to 705 and 277, to get

705 = 277 x 2 + 151

Step 2: Since the reminder 277 ≠ 0, we apply division lemma to 151 and 277, to get

277 = 151 x 1 + 126

Step 3: We consider the new divisor 151 and the new remainder 126, and apply the division lemma to get

151 = 126 x 1 + 25

We consider the new divisor 126 and the new remainder 25,and apply the division lemma to get

126 = 25 x 5 + 1

We consider the new divisor 25 and the new remainder 1,and apply the division lemma to get

25 = 1 x 25 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 277 and 705 is 1

Notice that 1 = HCF(25,1) = HCF(126,25) = HCF(151,126) = HCF(277,151) = HCF(705,277) .


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

Step 1: Since 647 > 1, we apply the division lemma to 647 and 1, to get

647 = 1 x 647 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 647 is 1

Notice that 1 = HCF(647,1) .
