HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 285, 739, 557 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 285, 739, 557 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 285, 739, 557 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 285, 739, 557 is 1.

HCF(285, 739, 557) = 1

Highest common factor (HCF) of 285, 739, 557 is 1.

Highest Common Factor of 285,739,557 using Euclid's algorithm

Highest Common Factor of 285,739,557 is 1

Step 1: Since 739 > 285, we apply the division lemma to 739 and 285, to get

739 = 285 x 2 + 169

Step 2: Since the reminder 285 ≠ 0, we apply division lemma to 169 and 285, to get

285 = 169 x 1 + 116

Step 3: We consider the new divisor 169 and the new remainder 116, and apply the division lemma to get

169 = 116 x 1 + 53

We consider the new divisor 116 and the new remainder 53,and apply the division lemma to get

116 = 53 x 2 + 10

We consider the new divisor 53 and the new remainder 10,and apply the division lemma to get

53 = 10 x 5 + 3

We consider the new divisor 10 and the new remainder 3,and apply the division lemma to get

10 = 3 x 3 + 1

We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get

3 = 1 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 285 and 739 is 1

Notice that 1 = HCF(3,1) = HCF(10,3) = HCF(53,10) = HCF(116,53) = HCF(169,116) = HCF(285,169) = HCF(739,285) .


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

Step 1: Since 557 > 1, we apply the division lemma to 557 and 1, to get

557 = 1 x 557 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 557 is 1

Notice that 1 = HCF(557,1) .
