HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 783, 666, 27 i.e. 9 the largest integer that leaves a remainder zero for all numbers.

HCF of 783, 666, 27 is 9 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 783, 666, 27 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 783, 666, 27 is 9.

HCF(783, 666, 27) = 9

HCF of 783, 666, 27 using Euclid's algorithm

Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.

HCF of:

Highest common factor (HCF) of 783, 666, 27 is 9.

Highest Common Factor of 783,666,27 using Euclid's algorithm

Highest Common Factor of 783,666,27 is 9

Step 1: Since 783 > 666, we apply the division lemma to 783 and 666, to get

783 = 666 x 1 + 117

Step 2: Since the reminder 666 ≠ 0, we apply division lemma to 117 and 666, to get

666 = 117 x 5 + 81

Step 3: We consider the new divisor 117 and the new remainder 81, and apply the division lemma to get

117 = 81 x 1 + 36

We consider the new divisor 81 and the new remainder 36,and apply the division lemma to get

81 = 36 x 2 + 9

We consider the new divisor 36 and the new remainder 9,and apply the division lemma to get

36 = 9 x 4 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 9, the HCF of 783 and 666 is 9

Notice that 9 = HCF(36,9) = HCF(81,36) = HCF(117,81) = HCF(666,117) = HCF(783,666) .


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

Step 1: Since 27 > 9, we apply the division lemma to 27 and 9, to get

27 = 9 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 9, the HCF of 9 and 27 is 9

Notice that 9 = HCF(27,9) .
