HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 252, 389, 802 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 252, 389, 802 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 252, 389, 802 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 252, 389, 802 is 1.

HCF(252, 389, 802) = 1

Highest common factor (HCF) of 252, 389, 802 is 1.

Highest Common Factor of 252,389,802 using Euclid's algorithm

Highest Common Factor of 252,389,802 is 1

Step 1: Since 389 > 252, we apply the division lemma to 389 and 252, to get

389 = 252 x 1 + 137

Step 2: Since the reminder 252 ≠ 0, we apply division lemma to 137 and 252, to get

252 = 137 x 1 + 115

Step 3: We consider the new divisor 137 and the new remainder 115, and apply the division lemma to get

137 = 115 x 1 + 22

We consider the new divisor 115 and the new remainder 22,and apply the division lemma to get

115 = 22 x 5 + 5

We consider the new divisor 22 and the new remainder 5,and apply the division lemma to get

22 = 5 x 4 + 2

We consider the new divisor 5 and the new remainder 2,and apply the division lemma to get

5 = 2 x 2 + 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 252 and 389 is 1

Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(22,5) = HCF(115,22) = HCF(137,115) = HCF(252,137) = HCF(389,252) .

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

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

802 = 1 x 802 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 802 is 1

Notice that 1 = HCF(802,1) .
