HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 983, 390 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 983, 390 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 983, 390 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 983, 390 is 1.

HCF(983, 390) = 1

Highest common factor (HCF) of 983, 390 is 1.

Highest Common Factor of 983,390 using Euclid's algorithm

Highest Common Factor of 983,390 is 1

Step 1: Since 983 > 390, we apply the division lemma to 983 and 390, to get

983 = 390 x 2 + 203

Step 2: Since the reminder 390 ≠ 0, we apply division lemma to 203 and 390, to get

390 = 203 x 1 + 187

Step 3: We consider the new divisor 203 and the new remainder 187, and apply the division lemma to get

203 = 187 x 1 + 16

We consider the new divisor 187 and the new remainder 16,and apply the division lemma to get

187 = 16 x 11 + 11

We consider the new divisor 16 and the new remainder 11,and apply the division lemma to get

16 = 11 x 1 + 5

We consider the new divisor 11 and the new remainder 5,and apply the division lemma to get

11 = 5 x 2 + 1

We consider the new divisor 5 and the new remainder 1,and apply the division lemma to get

5 = 1 x 5 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 983 and 390 is 1

Notice that 1 = HCF(5,1) = HCF(11,5) = HCF(16,11) = HCF(187,16) = HCF(203,187) = HCF(390,203) = HCF(983,390) .
