HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 577, 804, 87 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 577, 804, 87 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 577, 804, 87 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 577, 804, 87 is 1.

HCF(577, 804, 87) = 1

Highest common factor (HCF) of 577, 804, 87 is 1.

Highest Common Factor of 577,804,87 using Euclid's algorithm

Highest Common Factor of 577,804,87 is 1

Step 1: Since 804 > 577, we apply the division lemma to 804 and 577, to get

804 = 577 x 1 + 227

Step 2: Since the reminder 577 ≠ 0, we apply division lemma to 227 and 577, to get

577 = 227 x 2 + 123

Step 3: We consider the new divisor 227 and the new remainder 123, and apply the division lemma to get

227 = 123 x 1 + 104

We consider the new divisor 123 and the new remainder 104,and apply the division lemma to get

123 = 104 x 1 + 19

We consider the new divisor 104 and the new remainder 19,and apply the division lemma to get

104 = 19 x 5 + 9

We consider the new divisor 19 and the new remainder 9,and apply the division lemma to get

19 = 9 x 2 + 1

We consider the new divisor 9 and the new remainder 1,and apply the division lemma to get

9 = 1 x 9 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 577 and 804 is 1

Notice that 1 = HCF(9,1) = HCF(19,9) = HCF(104,19) = HCF(123,104) = HCF(227,123) = HCF(577,227) = HCF(804,577) .

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

Step 1: Since 87 > 1, we apply the division lemma to 87 and 1, to get

87 = 1 x 87 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 87 is 1

Notice that 1 = HCF(87,1) .
