HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 711, 434, 808 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 711, 434, 808 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 711, 434, 808 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 711, 434, 808 is 1.

HCF(711, 434, 808) = 1

Highest Common Factor of 711,434,808 using Euclid's algorithm

Highest Common Factor of 711,434,808 is 1

Step 1: Since 711 > 434, we apply the division lemma to 711 and 434, to get

711 = 434 x 1 + 277

Step 2: Since the reminder 434 ≠ 0, we apply division lemma to 277 and 434, to get

434 = 277 x 1 + 157

Step 3: We consider the new divisor 277 and the new remainder 157, and apply the division lemma to get

277 = 157 x 1 + 120

We consider the new divisor 157 and the new remainder 120,and apply the division lemma to get

157 = 120 x 1 + 37

We consider the new divisor 120 and the new remainder 37,and apply the division lemma to get

120 = 37 x 3 + 9

We consider the new divisor 37 and the new remainder 9,and apply the division lemma to get

37 = 9 x 4 + 1

We consider the new divisor 9 and the new remainder 1,and apply the division lemma to get

9 = 1 x 9 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 711 and 434 is 1

Notice that 1 = HCF(9,1) = HCF(37,9) = HCF(120,37) = HCF(157,120) = HCF(277,157) = HCF(434,277) = HCF(711,434) .

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

Step 1: Since 808 > 1, we apply the division lemma to 808 and 1, to get

808 = 1 x 808 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 808 is 1

Notice that 1 = HCF(808,1) .
