HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 777, 548, 685 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 777, 548, 685 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 777, 548, 685 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 777, 548, 685 is 1.

HCF(777, 548, 685) = 1

HCF of 777, 548, 685 using Euclid's algorithm

Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.

Highest common factor (HCF) of 777, 548, 685 is 1.

Highest Common Factor of 777,548,685 using Euclid's algorithm

Highest Common Factor of 777,548,685 is 1

Step 1: Since 777 > 548, we apply the division lemma to 777 and 548, to get

777 = 548 x 1 + 229

Step 2: Since the reminder 548 ≠ 0, we apply division lemma to 229 and 548, to get

548 = 229 x 2 + 90

Step 3: We consider the new divisor 229 and the new remainder 90, and apply the division lemma to get

229 = 90 x 2 + 49

We consider the new divisor 90 and the new remainder 49,and apply the division lemma to get

90 = 49 x 1 + 41

We consider the new divisor 49 and the new remainder 41,and apply the division lemma to get

49 = 41 x 1 + 8

We consider the new divisor 41 and the new remainder 8,and apply the division lemma to get

41 = 8 x 5 + 1

We consider the new divisor 8 and the new remainder 1,and apply the division lemma to get

8 = 1 x 8 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 777 and 548 is 1

Notice that 1 = HCF(8,1) = HCF(41,8) = HCF(49,41) = HCF(90,49) = HCF(229,90) = HCF(548,229) = HCF(777,548) .


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

Step 1: Since 685 > 1, we apply the division lemma to 685 and 1, to get

685 = 1 x 685 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 685 is 1

Notice that 1 = HCF(685,1) .
