HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 474, 806, 939 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 474, 806, 939 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 474, 806, 939 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 474, 806, 939 is 1.

HCF(474, 806, 939) = 1

Highest Common Factor of 474,806,939 using Euclid's algorithm

Highest Common Factor of 474,806,939 is 1

Step 1: Since 806 > 474, we apply the division lemma to 806 and 474, to get

806 = 474 x 1 + 332

Step 2: Since the reminder 474 ≠ 0, we apply division lemma to 332 and 474, to get

474 = 332 x 1 + 142

Step 3: We consider the new divisor 332 and the new remainder 142, and apply the division lemma to get

332 = 142 x 2 + 48

We consider the new divisor 142 and the new remainder 48,and apply the division lemma to get

142 = 48 x 2 + 46

We consider the new divisor 48 and the new remainder 46,and apply the division lemma to get

48 = 46 x 1 + 2

We consider the new divisor 46 and the new remainder 2,and apply the division lemma to get

46 = 2 x 23 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 474 and 806 is 2

Notice that 2 = HCF(46,2) = HCF(48,46) = HCF(142,48) = HCF(332,142) = HCF(474,332) = HCF(806,474) .

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

Step 1: Since 939 > 2, we apply the division lemma to 939 and 2, to get

939 = 2 x 469 + 1

Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, 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 2 and 939 is 1

Notice that 1 = HCF(2,1) = HCF(939,2) .
