HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 442, 777 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 442, 777 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 442, 777 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 442, 777 is 1.

HCF(442, 777) = 1

Highest common factor (HCF) of 442, 777 is 1.

Highest Common Factor of 442,777 using Euclid's algorithm

Highest Common Factor of 442,777 is 1

Step 1: Since 777 > 442, we apply the division lemma to 777 and 442, to get

777 = 442 x 1 + 335

Step 2: Since the reminder 442 ≠ 0, we apply division lemma to 335 and 442, to get

442 = 335 x 1 + 107

Step 3: We consider the new divisor 335 and the new remainder 107, and apply the division lemma to get

335 = 107 x 3 + 14

We consider the new divisor 107 and the new remainder 14,and apply the division lemma to get

107 = 14 x 7 + 9

We consider the new divisor 14 and the new remainder 9,and apply the division lemma to get

14 = 9 x 1 + 5

We consider the new divisor 9 and the new remainder 5,and apply the division lemma to get

9 = 5 x 1 + 4

We consider the new divisor 5 and the new remainder 4,and apply the division lemma to get

5 = 4 x 1 + 1

We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get

4 = 1 x 4 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 442 and 777 is 1

Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(9,5) = HCF(14,9) = HCF(107,14) = HCF(335,107) = HCF(442,335) = HCF(777,442) .
