HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 485, 666, 754 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 485, 666, 754 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 485, 666, 754 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 485, 666, 754 is 1.

HCF(485, 666, 754) = 1

HCF of 485, 666, 754 using Euclid's algorithm

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

Highest common factor (HCF) of 485, 666, 754 is 1.

Highest Common Factor of 485,666,754 using Euclid's algorithm

Highest Common Factor of 485,666,754 is 1

Step 1: Since 666 > 485, we apply the division lemma to 666 and 485, to get

666 = 485 x 1 + 181

Step 2: Since the reminder 485 ≠ 0, we apply division lemma to 181 and 485, to get

485 = 181 x 2 + 123

Step 3: We consider the new divisor 181 and the new remainder 123, and apply the division lemma to get

181 = 123 x 1 + 58

We consider the new divisor 123 and the new remainder 58,and apply the division lemma to get

123 = 58 x 2 + 7

We consider the new divisor 58 and the new remainder 7,and apply the division lemma to get

58 = 7 x 8 + 2

We consider the new divisor 7 and the new remainder 2,and apply the division lemma to get

7 = 2 x 3 + 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 485 and 666 is 1

Notice that 1 = HCF(2,1) = HCF(7,2) = HCF(58,7) = HCF(123,58) = HCF(181,123) = HCF(485,181) = HCF(666,485) .

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

Step 1: Since 754 > 1, we apply the division lemma to 754 and 1, to get

754 = 1 x 754 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 754 is 1

Notice that 1 = HCF(754,1) .
