HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 773, 943, 318, 442 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 773, 943, 318, 442 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 773, 943, 318, 442 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 773, 943, 318, 442 is 1.

HCF(773, 943, 318, 442) = 1

Highest common factor (HCF) of 773, 943, 318, 442 is 1.

Highest Common Factor of 773,943,318,442 using Euclid's algorithm

Highest Common Factor of 773,943,318,442 is 1

Step 1: Since 943 > 773, we apply the division lemma to 943 and 773, to get

943 = 773 x 1 + 170

Step 2: Since the reminder 773 ≠ 0, we apply division lemma to 170 and 773, to get

773 = 170 x 4 + 93

Step 3: We consider the new divisor 170 and the new remainder 93, and apply the division lemma to get

170 = 93 x 1 + 77

We consider the new divisor 93 and the new remainder 77,and apply the division lemma to get

93 = 77 x 1 + 16

We consider the new divisor 77 and the new remainder 16,and apply the division lemma to get

77 = 16 x 4 + 13

We consider the new divisor 16 and the new remainder 13,and apply the division lemma to get

16 = 13 x 1 + 3

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

13 = 3 x 4 + 1

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

3 = 1 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 773 and 943 is 1

Notice that 1 = HCF(3,1) = HCF(13,3) = HCF(16,13) = HCF(77,16) = HCF(93,77) = HCF(170,93) = HCF(773,170) = HCF(943,773) .

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

Step 1: Since 318 > 1, we apply the division lemma to 318 and 1, to get

318 = 1 x 318 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 318 is 1

Notice that 1 = HCF(318,1) .

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

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

442 = 1 x 442 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 442 is 1

Notice that 1 = HCF(442,1) .
