HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 298, 487, 712 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 298, 487, 712 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 298, 487, 712 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 298, 487, 712 is 1.

HCF(298, 487, 712) = 1

HCF of 298, 487, 712 using Euclid's algorithm

Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.

HCF of:

Highest common factor (HCF) of 298, 487, 712 is 1.

Highest Common Factor of 298,487,712 using Euclid's algorithm

Highest Common Factor of 298,487,712 is 1

Step 1: Since 487 > 298, we apply the division lemma to 487 and 298, to get

487 = 298 x 1 + 189

Step 2: Since the reminder 298 ≠ 0, we apply division lemma to 189 and 298, to get

298 = 189 x 1 + 109

Step 3: We consider the new divisor 189 and the new remainder 109, and apply the division lemma to get

189 = 109 x 1 + 80

We consider the new divisor 109 and the new remainder 80,and apply the division lemma to get

109 = 80 x 1 + 29

We consider the new divisor 80 and the new remainder 29,and apply the division lemma to get

80 = 29 x 2 + 22

We consider the new divisor 29 and the new remainder 22,and apply the division lemma to get

29 = 22 x 1 + 7

We consider the new divisor 22 and the new remainder 7,and apply the division lemma to get

22 = 7 x 3 + 1

We consider the new divisor 7 and the new remainder 1,and apply the division lemma to get

7 = 1 x 7 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 298 and 487 is 1

Notice that 1 = HCF(7,1) = HCF(22,7) = HCF(29,22) = HCF(80,29) = HCF(109,80) = HCF(189,109) = HCF(298,189) = HCF(487,298) .

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

Step 1: Since 712 > 1, we apply the division lemma to 712 and 1, to get

712 = 1 x 712 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 712 is 1

Notice that 1 = HCF(712,1) .
