HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 676, 570, 987 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 676, 570, 987 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 676, 570, 987 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 676, 570, 987 is 1.

HCF(676, 570, 987) = 1

Highest common factor (HCF) of 676, 570, 987 is 1.

Highest Common Factor of 676,570,987 using Euclid's algorithm

Highest Common Factor of 676,570,987 is 1

Step 1: Since 676 > 570, we apply the division lemma to 676 and 570, to get

676 = 570 x 1 + 106

Step 2: Since the reminder 570 ≠ 0, we apply division lemma to 106 and 570, to get

570 = 106 x 5 + 40

Step 3: We consider the new divisor 106 and the new remainder 40, and apply the division lemma to get

106 = 40 x 2 + 26

We consider the new divisor 40 and the new remainder 26,and apply the division lemma to get

40 = 26 x 1 + 14

We consider the new divisor 26 and the new remainder 14,and apply the division lemma to get

26 = 14 x 1 + 12

We consider the new divisor 14 and the new remainder 12,and apply the division lemma to get

14 = 12 x 1 + 2

We consider the new divisor 12 and the new remainder 2,and apply the division lemma to get

12 = 2 x 6 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 676 and 570 is 2

Notice that 2 = HCF(12,2) = HCF(14,12) = HCF(26,14) = HCF(40,26) = HCF(106,40) = HCF(570,106) = HCF(676,570) .

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

Step 1: Since 987 > 2, we apply the division lemma to 987 and 2, to get

987 = 2 x 493 + 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 987 is 1

Notice that 1 = HCF(2,1) = HCF(987,2) .
