HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 777, 671, 278, 423 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 777, 671, 278, 423 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, 671, 278, 423 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, 671, 278, 423 is 1.

HCF(777, 671, 278, 423) = 1

Highest common factor (HCF) of 777, 671, 278, 423 is 1.

Highest Common Factor of 777,671,278,423 using Euclid's algorithm

Highest Common Factor of 777,671,278,423 is 1

Step 1: Since 777 > 671, we apply the division lemma to 777 and 671, to get

777 = 671 x 1 + 106

Step 2: Since the reminder 671 ≠ 0, we apply division lemma to 106 and 671, to get

671 = 106 x 6 + 35

Step 3: We consider the new divisor 106 and the new remainder 35, and apply the division lemma to get

106 = 35 x 3 + 1

We consider the new divisor 35 and the new remainder 1, and apply the division lemma to get

35 = 1 x 35 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 777 and 671 is 1

Notice that 1 = HCF(35,1) = HCF(106,35) = HCF(671,106) = HCF(777,671) .


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

Step 1: Since 278 > 1, we apply the division lemma to 278 and 1, to get

278 = 1 x 278 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 278 is 1

Notice that 1 = HCF(278,1) .


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

Step 1: Since 423 > 1, we apply the division lemma to 423 and 1, to get

423 = 1 x 423 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 423 is 1

Notice that 1 = HCF(423,1) .
