HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 802, 708, 121 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 802, 708, 121 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 802, 708, 121 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 802, 708, 121 is 1.

HCF(802, 708, 121) = 1

Highest common factor (HCF) of 802, 708, 121 is 1.

Highest Common Factor of 802,708,121 using Euclid's algorithm

Highest Common Factor of 802,708,121 is 1

Step 1: Since 802 > 708, we apply the division lemma to 802 and 708, to get

802 = 708 x 1 + 94

Step 2: Since the reminder 708 ≠ 0, we apply division lemma to 94 and 708, to get

708 = 94 x 7 + 50

Step 3: We consider the new divisor 94 and the new remainder 50, and apply the division lemma to get

94 = 50 x 1 + 44

We consider the new divisor 50 and the new remainder 44,and apply the division lemma to get

50 = 44 x 1 + 6

We consider the new divisor 44 and the new remainder 6,and apply the division lemma to get

44 = 6 x 7 + 2

We consider the new divisor 6 and the new remainder 2,and apply the division lemma to get

6 = 2 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 802 and 708 is 2

Notice that 2 = HCF(6,2) = HCF(44,6) = HCF(50,44) = HCF(94,50) = HCF(708,94) = HCF(802,708) .

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

Step 1: Since 121 > 2, we apply the division lemma to 121 and 2, to get

121 = 2 x 60 + 1

Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, 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 2 and 121 is 1

Notice that 1 = HCF(2,1) = HCF(121,2) .
