HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 778, 350, 783, 817 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 778, 350, 783, 817 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 778, 350, 783, 817 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 778, 350, 783, 817 is 1.

HCF(778, 350, 783, 817) = 1

Highest common factor (HCF) of 778, 350, 783, 817 is 1.

Highest Common Factor of 778,350,783,817 using Euclid's algorithm

Highest Common Factor of 778,350,783,817 is 1

Step 1: Since 778 > 350, we apply the division lemma to 778 and 350, to get

778 = 350 x 2 + 78

Step 2: Since the reminder 350 ≠ 0, we apply division lemma to 78 and 350, to get

350 = 78 x 4 + 38

Step 3: We consider the new divisor 78 and the new remainder 38, and apply the division lemma to get

78 = 38 x 2 + 2

We consider the new divisor 38 and the new remainder 2, and apply the division lemma to get

38 = 2 x 19 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 778 and 350 is 2

Notice that 2 = HCF(38,2) = HCF(78,38) = HCF(350,78) = HCF(778,350) .


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

Step 1: Since 783 > 2, we apply the division lemma to 783 and 2, to get

783 = 2 x 391 + 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 783 is 1

Notice that 1 = HCF(2,1) = HCF(783,2) .


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

Step 1: Since 817 > 1, we apply the division lemma to 817 and 1, to get

817 = 1 x 817 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 817 is 1

Notice that 1 = HCF(817,1) .
