HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 361, 274, 688, 703 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 361, 274, 688, 703 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 361, 274, 688, 703 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 361, 274, 688, 703 is 1.

HCF(361, 274, 688, 703) = 1

Highest Common Factor of 361,274,688,703 using Euclid's algorithm

Highest Common Factor of 361,274,688,703 is 1

Step 1: Since 361 > 274, we apply the division lemma to 361 and 274, to get

361 = 274 x 1 + 87

Step 2: Since the reminder 274 ≠ 0, we apply division lemma to 87 and 274, to get

274 = 87 x 3 + 13

Step 3: We consider the new divisor 87 and the new remainder 13, and apply the division lemma to get

87 = 13 x 6 + 9

We consider the new divisor 13 and the new remainder 9,and apply the division lemma to get

13 = 9 x 1 + 4

We consider the new divisor 9 and the new remainder 4,and apply the division lemma to get

9 = 4 x 2 + 1

We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get

4 = 1 x 4 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 361 and 274 is 1

Notice that 1 = HCF(4,1) = HCF(9,4) = HCF(13,9) = HCF(87,13) = HCF(274,87) = HCF(361,274) .

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

Step 1: Since 688 > 1, we apply the division lemma to 688 and 1, to get

688 = 1 x 688 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 688 is 1

Notice that 1 = HCF(688,1) .

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

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

703 = 1 x 703 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 703 is 1

Notice that 1 = HCF(703,1) .
