HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 218, 702, 985 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 218, 702, 985 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 218, 702, 985 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 218, 702, 985 is 1.

HCF(218, 702, 985) = 1

Highest common factor (HCF) of 218, 702, 985 is 1.

Highest Common Factor of 218,702,985 using Euclid's algorithm

Highest Common Factor of 218,702,985 is 1

Step 1: Since 702 > 218, we apply the division lemma to 702 and 218, to get

702 = 218 x 3 + 48

Step 2: Since the reminder 218 ≠ 0, we apply division lemma to 48 and 218, to get

218 = 48 x 4 + 26

Step 3: We consider the new divisor 48 and the new remainder 26, and apply the division lemma to get

48 = 26 x 1 + 22

We consider the new divisor 26 and the new remainder 22,and apply the division lemma to get

26 = 22 x 1 + 4

We consider the new divisor 22 and the new remainder 4,and apply the division lemma to get

22 = 4 x 5 + 2

We consider the new divisor 4 and the new remainder 2,and apply the division lemma to get

4 = 2 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 218 and 702 is 2

Notice that 2 = HCF(4,2) = HCF(22,4) = HCF(26,22) = HCF(48,26) = HCF(218,48) = HCF(702,218) .

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

Step 1: Since 985 > 2, we apply the division lemma to 985 and 2, to get

985 = 2 x 492 + 1

Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, 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 2 and 985 is 1

Notice that 1 = HCF(2,1) = HCF(985,2) .
