HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 374, 978 i.e. 2 the largest integer that leaves a remainder zero for all numbers.

HCF of 374, 978 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 374, 978 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 374, 978 is 2.

HCF(374, 978) = 2

Highest common factor (HCF) of 374, 978 is 2.

Highest Common Factor of 374,978 using Euclid's algorithm

Highest Common Factor of 374,978 is 2

Step 1: Since 978 > 374, we apply the division lemma to 978 and 374, to get

978 = 374 x 2 + 230

Step 2: Since the reminder 374 ≠ 0, we apply division lemma to 230 and 374, to get

374 = 230 x 1 + 144

Step 3: We consider the new divisor 230 and the new remainder 144, and apply the division lemma to get

230 = 144 x 1 + 86

We consider the new divisor 144 and the new remainder 86,and apply the division lemma to get

144 = 86 x 1 + 58

We consider the new divisor 86 and the new remainder 58,and apply the division lemma to get

86 = 58 x 1 + 28

We consider the new divisor 58 and the new remainder 28,and apply the division lemma to get

58 = 28 x 2 + 2

We consider the new divisor 28 and the new remainder 2,and apply the division lemma to get

28 = 2 x 14 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 374 and 978 is 2

Notice that 2 = HCF(28,2) = HCF(58,28) = HCF(86,58) = HCF(144,86) = HCF(230,144) = HCF(374,230) = HCF(978,374) .
