HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 370, 217, 983 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 370, 217, 983 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 370, 217, 983 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 370, 217, 983 is 1.

HCF(370, 217, 983) = 1

HCF of 370, 217, 983 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 370, 217, 983 is 1.

Highest Common Factor of 370,217,983 using Euclid's algorithm

Highest Common Factor of 370,217,983 is 1

Step 1: Since 370 > 217, we apply the division lemma to 370 and 217, to get

370 = 217 x 1 + 153

Step 2: Since the reminder 217 ≠ 0, we apply division lemma to 153 and 217, to get

217 = 153 x 1 + 64

Step 3: We consider the new divisor 153 and the new remainder 64, and apply the division lemma to get

153 = 64 x 2 + 25

We consider the new divisor 64 and the new remainder 25,and apply the division lemma to get

64 = 25 x 2 + 14

We consider the new divisor 25 and the new remainder 14,and apply the division lemma to get

25 = 14 x 1 + 11

We consider the new divisor 14 and the new remainder 11,and apply the division lemma to get

14 = 11 x 1 + 3

We consider the new divisor 11 and the new remainder 3,and apply the division lemma to get

11 = 3 x 3 + 2

We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get

3 = 2 x 1 + 1

We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get

2 = 1 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 370 and 217 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(11,3) = HCF(14,11) = HCF(25,14) = HCF(64,25) = HCF(153,64) = HCF(217,153) = HCF(370,217) .

We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma

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

983 = 1 x 983 + 0

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

Notice that 1 = HCF(983,1) .
