HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 778, 534, 623 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 778, 534, 623 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, 534, 623 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, 534, 623 is 1.

HCF(778, 534, 623) = 1

Highest common factor (HCF) of 778, 534, 623 is 1.

Highest Common Factor of 778,534,623 using Euclid's algorithm

Highest Common Factor of 778,534,623 is 1

Step 1: Since 778 > 534, we apply the division lemma to 778 and 534, to get

778 = 534 x 1 + 244

Step 2: Since the reminder 534 ≠ 0, we apply division lemma to 244 and 534, to get

534 = 244 x 2 + 46

Step 3: We consider the new divisor 244 and the new remainder 46, and apply the division lemma to get

244 = 46 x 5 + 14

We consider the new divisor 46 and the new remainder 14,and apply the division lemma to get

46 = 14 x 3 + 4

We consider the new divisor 14 and the new remainder 4,and apply the division lemma to get

14 = 4 x 3 + 2

We consider the new divisor 4 and the new remainder 2,and apply the division lemma to get

4 = 2 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 778 and 534 is 2

Notice that 2 = HCF(4,2) = HCF(14,4) = HCF(46,14) = HCF(244,46) = HCF(534,244) = HCF(778,534) .


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

Step 1: Since 623 > 2, we apply the division lemma to 623 and 2, to get

623 = 2 x 311 + 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 623 is 1

Notice that 1 = HCF(2,1) = HCF(623,2) .
