HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 777, 121, 370 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 777, 121, 370 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 777, 121, 370 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 777, 121, 370 is 1.

HCF(777, 121, 370) = 1

Highest common factor (HCF) of 777, 121, 370 is 1.

Highest Common Factor of 777,121,370 using Euclid's algorithm

Highest Common Factor of 777,121,370 is 1

Step 1: Since 777 > 121, we apply the division lemma to 777 and 121, to get

777 = 121 x 6 + 51

Step 2: Since the reminder 121 ≠ 0, we apply division lemma to 51 and 121, to get

121 = 51 x 2 + 19

Step 3: We consider the new divisor 51 and the new remainder 19, and apply the division lemma to get

51 = 19 x 2 + 13

We consider the new divisor 19 and the new remainder 13,and apply the division lemma to get

19 = 13 x 1 + 6

We consider the new divisor 13 and the new remainder 6,and apply the division lemma to get

13 = 6 x 2 + 1

We consider the new divisor 6 and the new remainder 1,and apply the division lemma to get

6 = 1 x 6 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 777 and 121 is 1

Notice that 1 = HCF(6,1) = HCF(13,6) = HCF(19,13) = HCF(51,19) = HCF(121,51) = HCF(777,121) .

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

Step 1: Since 370 > 1, we apply the division lemma to 370 and 1, to get

370 = 1 x 370 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 370 is 1

Notice that 1 = HCF(370,1) .
