HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 984, 771, 160 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 984, 771, 160 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 984, 771, 160 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 984, 771, 160 is 1.

HCF(984, 771, 160) = 1

Highest common factor (HCF) of 984, 771, 160 is 1.

Highest Common Factor of 984,771,160 using Euclid's algorithm

Highest Common Factor of 984,771,160 is 1

Step 1: Since 984 > 771, we apply the division lemma to 984 and 771, to get

984 = 771 x 1 + 213

Step 2: Since the reminder 771 ≠ 0, we apply division lemma to 213 and 771, to get

771 = 213 x 3 + 132

Step 3: We consider the new divisor 213 and the new remainder 132, and apply the division lemma to get

213 = 132 x 1 + 81

We consider the new divisor 132 and the new remainder 81,and apply the division lemma to get

132 = 81 x 1 + 51

We consider the new divisor 81 and the new remainder 51,and apply the division lemma to get

81 = 51 x 1 + 30

We consider the new divisor 51 and the new remainder 30,and apply the division lemma to get

51 = 30 x 1 + 21

We consider the new divisor 30 and the new remainder 21,and apply the division lemma to get

30 = 21 x 1 + 9

We consider the new divisor 21 and the new remainder 9,and apply the division lemma to get

21 = 9 x 2 + 3

We consider the new divisor 9 and the new remainder 3,and apply the division lemma to get

9 = 3 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 984 and 771 is 3

Notice that 3 = HCF(9,3) = HCF(21,9) = HCF(30,21) = HCF(51,30) = HCF(81,51) = HCF(132,81) = HCF(213,132) = HCF(771,213) = HCF(984,771) .

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

Step 1: Since 160 > 3, we apply the division lemma to 160 and 3, to get

160 = 3 x 53 + 1

Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 1 and 3, to get

3 = 1 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 3 and 160 is 1

Notice that 1 = HCF(3,1) = HCF(160,3) .
