HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 783, 491, 955 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 783, 491, 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 783, 491, 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 783, 491, 955 is 1.

HCF(783, 491, 955) = 1

Highest common factor (HCF) of 783, 491, 955 is 1.

Highest Common Factor of 783,491,955 using Euclid's algorithm

Highest Common Factor of 783,491,955 is 1

Step 1: Since 783 > 491, we apply the division lemma to 783 and 491, to get

783 = 491 x 1 + 292

Step 2: Since the reminder 491 ≠ 0, we apply division lemma to 292 and 491, to get

491 = 292 x 1 + 199

Step 3: We consider the new divisor 292 and the new remainder 199, and apply the division lemma to get

292 = 199 x 1 + 93

We consider the new divisor 199 and the new remainder 93,and apply the division lemma to get

199 = 93 x 2 + 13

We consider the new divisor 93 and the new remainder 13,and apply the division lemma to get

93 = 13 x 7 + 2

We consider the new divisor 13 and the new remainder 2,and apply the division lemma to get

13 = 2 x 6 + 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 783 and 491 is 1

Notice that 1 = HCF(2,1) = HCF(13,2) = HCF(93,13) = HCF(199,93) = HCF(292,199) = HCF(491,292) = HCF(783,491) .

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

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

955 = 1 x 955 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 955 is 1

Notice that 1 = HCF(955,1) .
