HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 764, 684 i.e. 4 the largest integer that leaves a remainder zero for all numbers.

HCF of 764, 684 is 4 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 764, 684 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 764, 684 is 4.

HCF(764, 684) = 4

Highest common factor (HCF) of 764, 684 is 4.

Highest Common Factor of 764,684 using Euclid's algorithm

Highest Common Factor of 764,684 is 4

Step 1: Since 764 > 684, we apply the division lemma to 764 and 684, to get

764 = 684 x 1 + 80

Step 2: Since the reminder 684 ≠ 0, we apply division lemma to 80 and 684, to get

684 = 80 x 8 + 44

Step 3: We consider the new divisor 80 and the new remainder 44, and apply the division lemma to get

80 = 44 x 1 + 36

We consider the new divisor 44 and the new remainder 36,and apply the division lemma to get

44 = 36 x 1 + 8

We consider the new divisor 36 and the new remainder 8,and apply the division lemma to get

36 = 8 x 4 + 4

We consider the new divisor 8 and the new remainder 4,and apply the division lemma to get

8 = 4 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 764 and 684 is 4

Notice that 4 = HCF(8,4) = HCF(36,8) = HCF(44,36) = HCF(80,44) = HCF(684,80) = HCF(764,684) .
