HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 741, 77, 245 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 741, 77, 245 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 741, 77, 245 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 741, 77, 245 is 1.

HCF(741, 77, 245) = 1

HCF of 741, 77, 245 using Euclid's algorithm

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

Highest common factor (HCF) of 741, 77, 245 is 1.

Highest Common Factor of 741,77,245 using Euclid's algorithm

Highest Common Factor of 741,77,245 is 1

Step 1: Since 741 > 77, we apply the division lemma to 741 and 77, to get

741 = 77 x 9 + 48

Step 2: Since the reminder 77 ≠ 0, we apply division lemma to 48 and 77, to get

77 = 48 x 1 + 29

Step 3: We consider the new divisor 48 and the new remainder 29, and apply the division lemma to get

48 = 29 x 1 + 19

We consider the new divisor 29 and the new remainder 19,and apply the division lemma to get

29 = 19 x 1 + 10

We consider the new divisor 19 and the new remainder 10,and apply the division lemma to get

19 = 10 x 1 + 9

We consider the new divisor 10 and the new remainder 9,and apply the division lemma to get

10 = 9 x 1 + 1

We consider the new divisor 9 and the new remainder 1,and apply the division lemma to get

9 = 1 x 9 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 741 and 77 is 1

Notice that 1 = HCF(9,1) = HCF(10,9) = HCF(19,10) = HCF(29,19) = HCF(48,29) = HCF(77,48) = HCF(741,77) .


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

Step 1: Since 245 > 1, we apply the division lemma to 245 and 1, to get

245 = 1 x 245 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 245 is 1

Notice that 1 = HCF(245,1) .
