HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 666, 298 i.e. 2 the largest integer that leaves a remainder zero for all numbers.

HCF of 666, 298 is 2 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 666, 298 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 666, 298 is 2.

HCF(666, 298) = 2

HCF of 666, 298 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 666, 298 is 2.

Highest Common Factor of 666,298 using Euclid's algorithm

Highest Common Factor of 666,298 is 2

Step 1: Since 666 > 298, we apply the division lemma to 666 and 298, to get

666 = 298 x 2 + 70

Step 2: Since the reminder 298 ≠ 0, we apply division lemma to 70 and 298, to get

298 = 70 x 4 + 18

Step 3: We consider the new divisor 70 and the new remainder 18, and apply the division lemma to get

70 = 18 x 3 + 16

We consider the new divisor 18 and the new remainder 16,and apply the division lemma to get

18 = 16 x 1 + 2

We consider the new divisor 16 and the new remainder 2,and apply the division lemma to get

16 = 2 x 8 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 666 and 298 is 2

Notice that 2 = HCF(16,2) = HCF(18,16) = HCF(70,18) = HCF(298,70) = HCF(666,298) .
