HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 778, 563, 189 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 778, 563, 189 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, 563, 189 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, 563, 189 is 1.

HCF(778, 563, 189) = 1

Highest common factor (HCF) of 778, 563, 189 is 1.

Highest Common Factor of 778,563,189 using Euclid's algorithm

Highest Common Factor of 778,563,189 is 1

Step 1: Since 778 > 563, we apply the division lemma to 778 and 563, to get

778 = 563 x 1 + 215

Step 2: Since the reminder 563 ≠ 0, we apply division lemma to 215 and 563, to get

563 = 215 x 2 + 133

Step 3: We consider the new divisor 215 and the new remainder 133, and apply the division lemma to get

215 = 133 x 1 + 82

We consider the new divisor 133 and the new remainder 82,and apply the division lemma to get

133 = 82 x 1 + 51

We consider the new divisor 82 and the new remainder 51,and apply the division lemma to get

82 = 51 x 1 + 31

We consider the new divisor 51 and the new remainder 31,and apply the division lemma to get

51 = 31 x 1 + 20

We consider the new divisor 31 and the new remainder 20,and apply the division lemma to get

31 = 20 x 1 + 11

We consider the new divisor 20 and the new remainder 11,and apply the division lemma to get

20 = 11 x 1 + 9

We consider the new divisor 11 and the new remainder 9,and apply the division lemma to get

11 = 9 x 1 + 2

We consider the new divisor 9 and the new remainder 2,and apply the division lemma to get

9 = 2 x 4 + 1

We consider the new divisor 2 and the new remainder 1,and apply the division lemma 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 778 and 563 is 1

Notice that 1 = HCF(2,1) = HCF(9,2) = HCF(11,9) = HCF(20,11) = HCF(31,20) = HCF(51,31) = HCF(82,51) = HCF(133,82) = HCF(215,133) = HCF(563,215) = HCF(778,563) .

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

Step 1: Since 189 > 1, we apply the division lemma to 189 and 1, to get

189 = 1 x 189 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 189 is 1

Notice that 1 = HCF(189,1) .
