HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 703, 426, 386 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 703, 426, 386 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 703, 426, 386 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 703, 426, 386 is 1.

HCF(703, 426, 386) = 1

Highest common factor (HCF) of 703, 426, 386 is 1.

Highest Common Factor of 703,426,386 using Euclid's algorithm

Highest Common Factor of 703,426,386 is 1

Step 1: Since 703 > 426, we apply the division lemma to 703 and 426, to get

703 = 426 x 1 + 277

Step 2: Since the reminder 426 ≠ 0, we apply division lemma to 277 and 426, to get

426 = 277 x 1 + 149

Step 3: We consider the new divisor 277 and the new remainder 149, and apply the division lemma to get

277 = 149 x 1 + 128

We consider the new divisor 149 and the new remainder 128,and apply the division lemma to get

149 = 128 x 1 + 21

We consider the new divisor 128 and the new remainder 21,and apply the division lemma to get

128 = 21 x 6 + 2

We consider the new divisor 21 and the new remainder 2,and apply the division lemma to get

21 = 2 x 10 + 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 703 and 426 is 1

Notice that 1 = HCF(2,1) = HCF(21,2) = HCF(128,21) = HCF(149,128) = HCF(277,149) = HCF(426,277) = HCF(703,426) .

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

Step 1: Since 386 > 1, we apply the division lemma to 386 and 1, to get

386 = 1 x 386 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 386 is 1

Notice that 1 = HCF(386,1) .
