HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 435, 709 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 435, 709 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 435, 709 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 435, 709 is 1.

HCF(435, 709) = 1

Highest common factor (HCF) of 435, 709 is 1.

Highest Common Factor of 435,709 using Euclid's algorithm

Highest Common Factor of 435,709 is 1

Step 1: Since 709 > 435, we apply the division lemma to 709 and 435, to get

709 = 435 x 1 + 274

Step 2: Since the reminder 435 ≠ 0, we apply division lemma to 274 and 435, to get

435 = 274 x 1 + 161

Step 3: We consider the new divisor 274 and the new remainder 161, and apply the division lemma to get

274 = 161 x 1 + 113

We consider the new divisor 161 and the new remainder 113,and apply the division lemma to get

161 = 113 x 1 + 48

We consider the new divisor 113 and the new remainder 48,and apply the division lemma to get

113 = 48 x 2 + 17

We consider the new divisor 48 and the new remainder 17,and apply the division lemma to get

48 = 17 x 2 + 14

We consider the new divisor 17 and the new remainder 14,and apply the division lemma to get

17 = 14 x 1 + 3

We consider the new divisor 14 and the new remainder 3,and apply the division lemma to get

14 = 3 x 4 + 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 435 and 709 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(14,3) = HCF(17,14) = HCF(48,17) = HCF(113,48) = HCF(161,113) = HCF(274,161) = HCF(435,274) = HCF(709,435) .
