HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 989, 716, 84 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 989, 716, 84 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 989, 716, 84 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 989, 716, 84 is 1.

HCF(989, 716, 84) = 1

Highest common factor (HCF) of 989, 716, 84 is 1.

Highest Common Factor of 989,716,84 using Euclid's algorithm

Highest Common Factor of 989,716,84 is 1

Step 1: Since 989 > 716, we apply the division lemma to 989 and 716, to get

989 = 716 x 1 + 273

Step 2: Since the reminder 716 ≠ 0, we apply division lemma to 273 and 716, to get

716 = 273 x 2 + 170

Step 3: We consider the new divisor 273 and the new remainder 170, and apply the division lemma to get

273 = 170 x 1 + 103

We consider the new divisor 170 and the new remainder 103,and apply the division lemma to get

170 = 103 x 1 + 67

We consider the new divisor 103 and the new remainder 67,and apply the division lemma to get

103 = 67 x 1 + 36

We consider the new divisor 67 and the new remainder 36,and apply the division lemma to get

67 = 36 x 1 + 31

We consider the new divisor 36 and the new remainder 31,and apply the division lemma to get

36 = 31 x 1 + 5

We consider the new divisor 31 and the new remainder 5,and apply the division lemma to get

31 = 5 x 6 + 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 989 and 716 is 1

Notice that 1 = HCF(5,1) = HCF(31,5) = HCF(36,31) = HCF(67,36) = HCF(103,67) = HCF(170,103) = HCF(273,170) = HCF(716,273) = HCF(989,716) .

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

Step 1: Since 84 > 1, we apply the division lemma to 84 and 1, to get

84 = 1 x 84 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 84 is 1

Notice that 1 = HCF(84,1) .
