HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 84, 658 i.e. 14 the largest integer that leaves a remainder zero for all numbers.

HCF of 84, 658 is 14 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 84, 658 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 84, 658 is 14.

HCF(84, 658) = 14

HCF of 84, 658 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 84, 658 is 14.

Highest Common Factor of 84,658 using Euclid's algorithm

Highest Common Factor of 84,658 is 14

Step 1: Since 658 > 84, we apply the division lemma to 658 and 84, to get

658 = 84 x 7 + 70

Step 2: Since the reminder 84 ≠ 0, we apply division lemma to 70 and 84, to get

84 = 70 x 1 + 14

Step 3: We consider the new divisor 70 and the new remainder 14, and apply the division lemma to get

70 = 14 x 5 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 14, the HCF of 84 and 658 is 14

Notice that 14 = HCF(70,14) = HCF(84,70) = HCF(658,84) .
