HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 504, 311, 744, 66 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 504, 311, 744, 66 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 504, 311, 744, 66 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 504, 311, 744, 66 is 1.

HCF(504, 311, 744, 66) = 1

Highest Common Factor of 504,311,744,66 using Euclid's algorithm

Highest Common Factor of 504,311,744,66 is 1

Step 1: Since 504 > 311, we apply the division lemma to 504 and 311, to get

504 = 311 x 1 + 193

Step 2: Since the reminder 311 ≠ 0, we apply division lemma to 193 and 311, to get

311 = 193 x 1 + 118

Step 3: We consider the new divisor 193 and the new remainder 118, and apply the division lemma to get

193 = 118 x 1 + 75

We consider the new divisor 118 and the new remainder 75,and apply the division lemma to get

118 = 75 x 1 + 43

We consider the new divisor 75 and the new remainder 43,and apply the division lemma to get

75 = 43 x 1 + 32

We consider the new divisor 43 and the new remainder 32,and apply the division lemma to get

43 = 32 x 1 + 11

We consider the new divisor 32 and the new remainder 11,and apply the division lemma to get

32 = 11 x 2 + 10

We consider the new divisor 11 and the new remainder 10,and apply the division lemma to get

11 = 10 x 1 + 1

We consider the new divisor 10 and the new remainder 1,and apply the division lemma to get

10 = 1 x 10 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 504 and 311 is 1

Notice that 1 = HCF(10,1) = HCF(11,10) = HCF(32,11) = HCF(43,32) = HCF(75,43) = HCF(118,75) = HCF(193,118) = HCF(311,193) = HCF(504,311) .


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

Step 1: Since 744 > 1, we apply the division lemma to 744 and 1, to get

744 = 1 x 744 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 744 is 1

Notice that 1 = HCF(744,1) .


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

Step 1: Since 66 > 1, we apply the division lemma to 66 and 1, to get

66 = 1 x 66 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 66 is 1

Notice that 1 = HCF(66,1) .
