HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 786, 504, 611 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 786, 504, 611 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 786, 504, 611 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 786, 504, 611 is 1.

HCF(786, 504, 611) = 1

Highest Common Factor of 786,504,611 using Euclid's algorithm

Highest Common Factor of 786,504,611 is 1

Step 1: Since 786 > 504, we apply the division lemma to 786 and 504, to get

786 = 504 x 1 + 282

Step 2: Since the reminder 504 ≠ 0, we apply division lemma to 282 and 504, to get

504 = 282 x 1 + 222

Step 3: We consider the new divisor 282 and the new remainder 222, and apply the division lemma to get

282 = 222 x 1 + 60

We consider the new divisor 222 and the new remainder 60,and apply the division lemma to get

222 = 60 x 3 + 42

We consider the new divisor 60 and the new remainder 42,and apply the division lemma to get

60 = 42 x 1 + 18

We consider the new divisor 42 and the new remainder 18,and apply the division lemma to get

42 = 18 x 2 + 6

We consider the new divisor 18 and the new remainder 6,and apply the division lemma to get

18 = 6 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 6, the HCF of 786 and 504 is 6

Notice that 6 = HCF(18,6) = HCF(42,18) = HCF(60,42) = HCF(222,60) = HCF(282,222) = HCF(504,282) = HCF(786,504) .

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

Step 1: Since 611 > 6, we apply the division lemma to 611 and 6, to get

611 = 6 x 101 + 5

Step 2: Since the reminder 6 ≠ 0, we apply division lemma to 5 and 6, to get

6 = 5 x 1 + 1

Step 3: We consider the new divisor 5 and the new remainder 1, and apply the division lemma to get

5 = 1 x 5 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 6 and 611 is 1

Notice that 1 = HCF(5,1) = HCF(6,5) = HCF(611,6) .
