HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 498, 770, 955 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 498, 770, 955 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 498, 770, 955 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 498, 770, 955 is 1.

HCF(498, 770, 955) = 1

Highest common factor (HCF) of 498, 770, 955 is 1.

Highest Common Factor of 498,770,955 using Euclid's algorithm

Highest Common Factor of 498,770,955 is 1

Step 1: Since 770 > 498, we apply the division lemma to 770 and 498, to get

770 = 498 x 1 + 272

Step 2: Since the reminder 498 ≠ 0, we apply division lemma to 272 and 498, to get

498 = 272 x 1 + 226

Step 3: We consider the new divisor 272 and the new remainder 226, and apply the division lemma to get

272 = 226 x 1 + 46

We consider the new divisor 226 and the new remainder 46,and apply the division lemma to get

226 = 46 x 4 + 42

We consider the new divisor 46 and the new remainder 42,and apply the division lemma to get

46 = 42 x 1 + 4

We consider the new divisor 42 and the new remainder 4,and apply the division lemma to get

42 = 4 x 10 + 2

We consider the new divisor 4 and the new remainder 2,and apply the division lemma to get

4 = 2 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 498 and 770 is 2

Notice that 2 = HCF(4,2) = HCF(42,4) = HCF(46,42) = HCF(226,46) = HCF(272,226) = HCF(498,272) = HCF(770,498) .


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

Step 1: Since 955 > 2, we apply the division lemma to 955 and 2, to get

955 = 2 x 477 + 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 955 is 1

Notice that 1 = HCF(2,1) = HCF(955,2) .
