HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 739, 205, 492 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 739, 205, 492 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 739, 205, 492 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 739, 205, 492 is 1.

HCF(739, 205, 492) = 1

Highest common factor (HCF) of 739, 205, 492 is 1.

Highest Common Factor of 739,205,492 using Euclid's algorithm

Highest Common Factor of 739,205,492 is 1

Step 1: Since 739 > 205, we apply the division lemma to 739 and 205, to get

739 = 205 x 3 + 124

Step 2: Since the reminder 205 ≠ 0, we apply division lemma to 124 and 205, to get

205 = 124 x 1 + 81

Step 3: We consider the new divisor 124 and the new remainder 81, and apply the division lemma to get

124 = 81 x 1 + 43

We consider the new divisor 81 and the new remainder 43,and apply the division lemma to get

81 = 43 x 1 + 38

We consider the new divisor 43 and the new remainder 38,and apply the division lemma to get

43 = 38 x 1 + 5

We consider the new divisor 38 and the new remainder 5,and apply the division lemma to get

38 = 5 x 7 + 3

We consider the new divisor 5 and the new remainder 3,and apply the division lemma to get

5 = 3 x 1 + 2

We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get

3 = 2 x 1 + 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 739 and 205 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(38,5) = HCF(43,38) = HCF(81,43) = HCF(124,81) = HCF(205,124) = HCF(739,205) .

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

Step 1: Since 492 > 1, we apply the division lemma to 492 and 1, to get

492 = 1 x 492 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 492 is 1

Notice that 1 = HCF(492,1) .
