HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 973, 228, 781 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 973, 228, 781 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 973, 228, 781 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 973, 228, 781 is 1.

HCF(973, 228, 781) = 1

Highest common factor (HCF) of 973, 228, 781 is 1.

Highest Common Factor of 973,228,781 using Euclid's algorithm

Highest Common Factor of 973,228,781 is 1

Step 1: Since 973 > 228, we apply the division lemma to 973 and 228, to get

973 = 228 x 4 + 61

Step 2: Since the reminder 228 ≠ 0, we apply division lemma to 61 and 228, to get

228 = 61 x 3 + 45

Step 3: We consider the new divisor 61 and the new remainder 45, and apply the division lemma to get

61 = 45 x 1 + 16

We consider the new divisor 45 and the new remainder 16,and apply the division lemma to get

45 = 16 x 2 + 13

We consider the new divisor 16 and the new remainder 13,and apply the division lemma to get

16 = 13 x 1 + 3

We consider the new divisor 13 and the new remainder 3,and apply the division lemma to get

13 = 3 x 4 + 1

We consider the new divisor 3 and the new remainder 1,and apply the division lemma 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 973 and 228 is 1

Notice that 1 = HCF(3,1) = HCF(13,3) = HCF(16,13) = HCF(45,16) = HCF(61,45) = HCF(228,61) = HCF(973,228) .

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

Step 1: Since 781 > 1, we apply the division lemma to 781 and 1, to get

781 = 1 x 781 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 781 is 1

Notice that 1 = HCF(781,1) .
