HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 922, 720, 977, 549 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 922, 720, 977, 549 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 922, 720, 977, 549 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 922, 720, 977, 549 is 1.

HCF(922, 720, 977, 549) = 1

Highest common factor (HCF) of 922, 720, 977, 549 is 1.

Highest Common Factor of 922,720,977,549 using Euclid's algorithm

Highest Common Factor of 922,720,977,549 is 1

Step 1: Since 922 > 720, we apply the division lemma to 922 and 720, to get

922 = 720 x 1 + 202

Step 2: Since the reminder 720 ≠ 0, we apply division lemma to 202 and 720, to get

720 = 202 x 3 + 114

Step 3: We consider the new divisor 202 and the new remainder 114, and apply the division lemma to get

202 = 114 x 1 + 88

We consider the new divisor 114 and the new remainder 88,and apply the division lemma to get

114 = 88 x 1 + 26

We consider the new divisor 88 and the new remainder 26,and apply the division lemma to get

88 = 26 x 3 + 10

We consider the new divisor 26 and the new remainder 10,and apply the division lemma to get

26 = 10 x 2 + 6

We consider the new divisor 10 and the new remainder 6,and apply the division lemma to get

10 = 6 x 1 + 4

We consider the new divisor 6 and the new remainder 4,and apply the division lemma to get

6 = 4 x 1 + 2

We consider the new divisor 4 and the new remainder 2,and apply the division lemma to get

4 = 2 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 922 and 720 is 2

Notice that 2 = HCF(4,2) = HCF(6,4) = HCF(10,6) = HCF(26,10) = HCF(88,26) = HCF(114,88) = HCF(202,114) = HCF(720,202) = HCF(922,720) .

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

Step 1: Since 977 > 2, we apply the division lemma to 977 and 2, to get

977 = 2 x 488 + 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 977 is 1

Notice that 1 = HCF(2,1) = HCF(977,2) .

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

Step 1: Since 549 > 1, we apply the division lemma to 549 and 1, to get

549 = 1 x 549 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 549 is 1

Notice that 1 = HCF(549,1) .
