HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 168, 781, 703 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 168, 781, 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 168, 781, 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 168, 781, 703 is 1.

HCF(168, 781, 703) = 1

Highest common factor (HCF) of 168, 781, 703 is 1.

Highest Common Factor of 168,781,703 using Euclid's algorithm

Highest Common Factor of 168,781,703 is 1

Step 1: Since 781 > 168, we apply the division lemma to 781 and 168, to get

781 = 168 x 4 + 109

Step 2: Since the reminder 168 ≠ 0, we apply division lemma to 109 and 168, to get

168 = 109 x 1 + 59

Step 3: We consider the new divisor 109 and the new remainder 59, and apply the division lemma to get

109 = 59 x 1 + 50

We consider the new divisor 59 and the new remainder 50,and apply the division lemma to get

59 = 50 x 1 + 9

We consider the new divisor 50 and the new remainder 9,and apply the division lemma to get

50 = 9 x 5 + 5

We consider the new divisor 9 and the new remainder 5,and apply the division lemma to get

9 = 5 x 1 + 4

We consider the new divisor 5 and the new remainder 4,and apply the division lemma to get

5 = 4 x 1 + 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 168 and 781 is 1

Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(9,5) = HCF(50,9) = HCF(59,50) = HCF(109,59) = HCF(168,109) = HCF(781,168) .

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) .
