HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 938, 798, 265 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 938, 798, 265 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 938, 798, 265 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 938, 798, 265 is 1.

HCF(938, 798, 265) = 1

Highest common factor (HCF) of 938, 798, 265 is 1.

Highest Common Factor of 938,798,265 using Euclid's algorithm

Highest Common Factor of 938,798,265 is 1

Step 1: Since 938 > 798, we apply the division lemma to 938 and 798, to get

938 = 798 x 1 + 140

Step 2: Since the reminder 798 ≠ 0, we apply division lemma to 140 and 798, to get

798 = 140 x 5 + 98

Step 3: We consider the new divisor 140 and the new remainder 98, and apply the division lemma to get

140 = 98 x 1 + 42

We consider the new divisor 98 and the new remainder 42,and apply the division lemma to get

98 = 42 x 2 + 14

We consider the new divisor 42 and the new remainder 14,and apply the division lemma to get

42 = 14 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 14, the HCF of 938 and 798 is 14

Notice that 14 = HCF(42,14) = HCF(98,42) = HCF(140,98) = HCF(798,140) = HCF(938,798) .

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

Step 1: Since 265 > 14, we apply the division lemma to 265 and 14, to get

265 = 14 x 18 + 13

Step 2: Since the reminder 14 ≠ 0, we apply division lemma to 13 and 14, to get

14 = 13 x 1 + 1

Step 3: We consider the new divisor 13 and the new remainder 1, and apply the division lemma to get

13 = 1 x 13 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 14 and 265 is 1

Notice that 1 = HCF(13,1) = HCF(14,13) = HCF(265,14) .
