HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 921, 733, 786 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 921, 733, 786 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 921, 733, 786 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 921, 733, 786 is 1.

HCF(921, 733, 786) = 1

Highest common factor (HCF) of 921, 733, 786 is 1.

Highest Common Factor of 921,733,786 using Euclid's algorithm

Highest Common Factor of 921,733,786 is 1

Step 1: Since 921 > 733, we apply the division lemma to 921 and 733, to get

921 = 733 x 1 + 188

Step 2: Since the reminder 733 ≠ 0, we apply division lemma to 188 and 733, to get

733 = 188 x 3 + 169

Step 3: We consider the new divisor 188 and the new remainder 169, and apply the division lemma to get

188 = 169 x 1 + 19

We consider the new divisor 169 and the new remainder 19,and apply the division lemma to get

169 = 19 x 8 + 17

We consider the new divisor 19 and the new remainder 17,and apply the division lemma to get

19 = 17 x 1 + 2

We consider the new divisor 17 and the new remainder 2,and apply the division lemma to get

17 = 2 x 8 + 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 921 and 733 is 1

Notice that 1 = HCF(2,1) = HCF(17,2) = HCF(19,17) = HCF(169,19) = HCF(188,169) = HCF(733,188) = HCF(921,733) .

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

Step 1: Since 786 > 1, we apply the division lemma to 786 and 1, to get

786 = 1 x 786 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 786 is 1

Notice that 1 = HCF(786,1) .
