HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 784, 211 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 784, 211 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 784, 211 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 784, 211 is 1.

HCF(784, 211) = 1

Highest common factor (HCF) of 784, 211 is 1.

Highest Common Factor of 784,211 using Euclid's algorithm

Highest Common Factor of 784,211 is 1

Step 1: Since 784 > 211, we apply the division lemma to 784 and 211, to get

784 = 211 x 3 + 151

Step 2: Since the reminder 211 ≠ 0, we apply division lemma to 151 and 211, to get

211 = 151 x 1 + 60

Step 3: We consider the new divisor 151 and the new remainder 60, and apply the division lemma to get

151 = 60 x 2 + 31

We consider the new divisor 60 and the new remainder 31,and apply the division lemma to get

60 = 31 x 1 + 29

We consider the new divisor 31 and the new remainder 29,and apply the division lemma to get

31 = 29 x 1 + 2

We consider the new divisor 29 and the new remainder 2,and apply the division lemma to get

29 = 2 x 14 + 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 784 and 211 is 1

Notice that 1 = HCF(2,1) = HCF(29,2) = HCF(31,29) = HCF(60,31) = HCF(151,60) = HCF(211,151) = HCF(784,211) .
