HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 778, 570, 529 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 778, 570, 529 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, 570, 529 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, 570, 529 is 1.

HCF(778, 570, 529) = 1

Highest common factor (HCF) of 778, 570, 529 is 1.

Highest Common Factor of 778,570,529 using Euclid's algorithm

Highest Common Factor of 778,570,529 is 1

Step 1: Since 778 > 570, we apply the division lemma to 778 and 570, to get

778 = 570 x 1 + 208

Step 2: Since the reminder 570 ≠ 0, we apply division lemma to 208 and 570, to get

570 = 208 x 2 + 154

Step 3: We consider the new divisor 208 and the new remainder 154, and apply the division lemma to get

208 = 154 x 1 + 54

We consider the new divisor 154 and the new remainder 54,and apply the division lemma to get

154 = 54 x 2 + 46

We consider the new divisor 54 and the new remainder 46,and apply the division lemma to get

54 = 46 x 1 + 8

We consider the new divisor 46 and the new remainder 8,and apply the division lemma to get

46 = 8 x 5 + 6

We consider the new divisor 8 and the new remainder 6,and apply the division lemma to get

8 = 6 x 1 + 2

We consider the new divisor 6 and the new remainder 2,and apply the division lemma to get

6 = 2 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 778 and 570 is 2

Notice that 2 = HCF(6,2) = HCF(8,6) = HCF(46,8) = HCF(54,46) = HCF(154,54) = HCF(208,154) = HCF(570,208) = HCF(778,570) .

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

Step 1: Since 529 > 2, we apply the division lemma to 529 and 2, to get

529 = 2 x 264 + 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 529 is 1

Notice that 1 = HCF(2,1) = HCF(529,2) .
