HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 393, 84346 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 393, 84346 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 393, 84346 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 393, 84346 is 1.

HCF(393, 84346) = 1

Highest common factor (HCF) of 393, 84346 is 1.

Highest Common Factor of 393,84346 using Euclid's algorithm

Highest Common Factor of 393,84346 is 1

Step 1: Since 84346 > 393, we apply the division lemma to 84346 and 393, to get

84346 = 393 x 214 + 244

Step 2: Since the reminder 393 ≠ 0, we apply division lemma to 244 and 393, to get

393 = 244 x 1 + 149

Step 3: We consider the new divisor 244 and the new remainder 149, and apply the division lemma to get

244 = 149 x 1 + 95

We consider the new divisor 149 and the new remainder 95,and apply the division lemma to get

149 = 95 x 1 + 54

We consider the new divisor 95 and the new remainder 54,and apply the division lemma to get

95 = 54 x 1 + 41

We consider the new divisor 54 and the new remainder 41,and apply the division lemma to get

54 = 41 x 1 + 13

We consider the new divisor 41 and the new remainder 13,and apply the division lemma to get

41 = 13 x 3 + 2

We consider the new divisor 13 and the new remainder 2,and apply the division lemma to get

13 = 2 x 6 + 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 393 and 84346 is 1

Notice that 1 = HCF(2,1) = HCF(13,2) = HCF(41,13) = HCF(54,41) = HCF(95,54) = HCF(149,95) = HCF(244,149) = HCF(393,244) = HCF(84346,393) .
