HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 985, 818, 528 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 985, 818, 528 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 985, 818, 528 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 985, 818, 528 is 1.

HCF(985, 818, 528) = 1

Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.

HCF of:

Highest common factor (HCF) of 985, 818, 528 is 1.

Highest Common Factor of 985,818,528 using Euclid's algorithm

Highest Common Factor of 985,818,528 is 1

Step 1: Since 985 > 818, we apply the division lemma to 985 and 818, to get

985 = 818 x 1 + 167

Step 2: Since the reminder 818 ≠ 0, we apply division lemma to 167 and 818, to get

818 = 167 x 4 + 150

Step 3: We consider the new divisor 167 and the new remainder 150, and apply the division lemma to get

167 = 150 x 1 + 17

We consider the new divisor 150 and the new remainder 17,and apply the division lemma to get

150 = 17 x 8 + 14

We consider the new divisor 17 and the new remainder 14,and apply the division lemma to get

17 = 14 x 1 + 3

We consider the new divisor 14 and the new remainder 3,and apply the division lemma to get

14 = 3 x 4 + 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 985 and 818 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(14,3) = HCF(17,14) = HCF(150,17) = HCF(167,150) = HCF(818,167) = HCF(985,818) .

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

Step 1: Since 528 > 1, we apply the division lemma to 528 and 1, to get

528 = 1 x 528 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 528 is 1

Notice that 1 = HCF(528,1) .
