HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 577, 126, 802 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 577, 126, 802 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, 126, 802 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, 126, 802 is 1.

HCF(577, 126, 802) = 1

Highest common factor (HCF) of 577, 126, 802 is 1.

Highest Common Factor of 577,126,802 using Euclid's algorithm

Highest Common Factor of 577,126,802 is 1

Step 1: Since 577 > 126, we apply the division lemma to 577 and 126, to get

577 = 126 x 4 + 73

Step 2: Since the reminder 126 ≠ 0, we apply division lemma to 73 and 126, to get

126 = 73 x 1 + 53

Step 3: We consider the new divisor 73 and the new remainder 53, and apply the division lemma to get

73 = 53 x 1 + 20

We consider the new divisor 53 and the new remainder 20,and apply the division lemma to get

53 = 20 x 2 + 13

We consider the new divisor 20 and the new remainder 13,and apply the division lemma to get

20 = 13 x 1 + 7

We consider the new divisor 13 and the new remainder 7,and apply the division lemma to get

13 = 7 x 1 + 6

We consider the new divisor 7 and the new remainder 6,and apply the division lemma to get

7 = 6 x 1 + 1

We consider the new divisor 6 and the new remainder 1,and apply the division lemma to get

6 = 1 x 6 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 577 and 126 is 1

Notice that 1 = HCF(6,1) = HCF(7,6) = HCF(13,7) = HCF(20,13) = HCF(53,20) = HCF(73,53) = HCF(126,73) = HCF(577,126) .

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

Step 1: Since 802 > 1, we apply the division lemma to 802 and 1, to get

802 = 1 x 802 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 802 is 1

Notice that 1 = HCF(802,1) .
