HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 434, 702, 396 i.e. 2 the largest integer that leaves a remainder zero for all numbers.

HCF of 434, 702, 396 is 2 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 434, 702, 396 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 434, 702, 396 is 2.

HCF(434, 702, 396) = 2

Highest common factor (HCF) of 434, 702, 396 is 2.

Highest Common Factor of 434,702,396 using Euclid's algorithm

Highest Common Factor of 434,702,396 is 2

Step 1: Since 702 > 434, we apply the division lemma to 702 and 434, to get

702 = 434 x 1 + 268

Step 2: Since the reminder 434 ≠ 0, we apply division lemma to 268 and 434, to get

434 = 268 x 1 + 166

Step 3: We consider the new divisor 268 and the new remainder 166, and apply the division lemma to get

268 = 166 x 1 + 102

We consider the new divisor 166 and the new remainder 102,and apply the division lemma to get

166 = 102 x 1 + 64

We consider the new divisor 102 and the new remainder 64,and apply the division lemma to get

102 = 64 x 1 + 38

We consider the new divisor 64 and the new remainder 38,and apply the division lemma to get

64 = 38 x 1 + 26

We consider the new divisor 38 and the new remainder 26,and apply the division lemma to get

38 = 26 x 1 + 12

We consider the new divisor 26 and the new remainder 12,and apply the division lemma to get

26 = 12 x 2 + 2

We consider the new divisor 12 and the new remainder 2,and apply the division lemma to get

12 = 2 x 6 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 434 and 702 is 2

Notice that 2 = HCF(12,2) = HCF(26,12) = HCF(38,26) = HCF(64,38) = HCF(102,64) = HCF(166,102) = HCF(268,166) = HCF(434,268) = HCF(702,434) .

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

Step 1: Since 396 > 2, we apply the division lemma to 396 and 2, to get

396 = 2 x 198 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 396 is 2

Notice that 2 = HCF(396,2) .
