HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 786, 442, 959 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 786, 442, 959 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 786, 442, 959 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 786, 442, 959 is 1.

HCF(786, 442, 959) = 1

Highest common factor (HCF) of 786, 442, 959 is 1.

Highest Common Factor of 786,442,959 using Euclid's algorithm

Highest Common Factor of 786,442,959 is 1

Step 1: Since 786 > 442, we apply the division lemma to 786 and 442, to get

786 = 442 x 1 + 344

Step 2: Since the reminder 442 ≠ 0, we apply division lemma to 344 and 442, to get

442 = 344 x 1 + 98

Step 3: We consider the new divisor 344 and the new remainder 98, and apply the division lemma to get

344 = 98 x 3 + 50

We consider the new divisor 98 and the new remainder 50,and apply the division lemma to get

98 = 50 x 1 + 48

We consider the new divisor 50 and the new remainder 48,and apply the division lemma to get

50 = 48 x 1 + 2

We consider the new divisor 48 and the new remainder 2,and apply the division lemma to get

48 = 2 x 24 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 786 and 442 is 2

Notice that 2 = HCF(48,2) = HCF(50,48) = HCF(98,50) = HCF(344,98) = HCF(442,344) = HCF(786,442) .

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

Step 1: Since 959 > 2, we apply the division lemma to 959 and 2, to get

959 = 2 x 479 + 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 959 is 1

Notice that 1 = HCF(2,1) = HCF(959,2) .
