HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 774, 479, 411 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 774, 479, 411 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 774, 479, 411 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 774, 479, 411 is 1.

HCF(774, 479, 411) = 1

Highest common factor (HCF) of 774, 479, 411 is 1.

Highest Common Factor of 774,479,411 using Euclid's algorithm

Highest Common Factor of 774,479,411 is 1

Step 1: Since 774 > 479, we apply the division lemma to 774 and 479, to get

774 = 479 x 1 + 295

Step 2: Since the reminder 479 ≠ 0, we apply division lemma to 295 and 479, to get

479 = 295 x 1 + 184

Step 3: We consider the new divisor 295 and the new remainder 184, and apply the division lemma to get

295 = 184 x 1 + 111

We consider the new divisor 184 and the new remainder 111,and apply the division lemma to get

184 = 111 x 1 + 73

We consider the new divisor 111 and the new remainder 73,and apply the division lemma to get

111 = 73 x 1 + 38

We consider the new divisor 73 and the new remainder 38,and apply the division lemma to get

73 = 38 x 1 + 35

We consider the new divisor 38 and the new remainder 35,and apply the division lemma to get

38 = 35 x 1 + 3

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

35 = 3 x 11 + 2

We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get

3 = 2 x 1 + 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 774 and 479 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(35,3) = HCF(38,35) = HCF(73,38) = HCF(111,73) = HCF(184,111) = HCF(295,184) = HCF(479,295) = HCF(774,479) .

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

Step 1: Since 411 > 1, we apply the division lemma to 411 and 1, to get

411 = 1 x 411 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 411 is 1

Notice that 1 = HCF(411,1) .
