HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 7477, 1638, 59390 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 7477, 1638, 59390 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 7477, 1638, 59390 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 7477, 1638, 59390 is 1.

HCF(7477, 1638, 59390) = 1

Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.

HCF of:

Highest common factor (HCF) of 7477, 1638, 59390 is 1.

Highest Common Factor of 7477,1638,59390 using Euclid's algorithm

Highest Common Factor of 7477,1638,59390 is 1

Step 1: Since 7477 > 1638, we apply the division lemma to 7477 and 1638, to get

7477 = 1638 x 4 + 925

Step 2: Since the reminder 1638 ≠ 0, we apply division lemma to 925 and 1638, to get

1638 = 925 x 1 + 713

Step 3: We consider the new divisor 925 and the new remainder 713, and apply the division lemma to get

925 = 713 x 1 + 212

We consider the new divisor 713 and the new remainder 212,and apply the division lemma to get

713 = 212 x 3 + 77

We consider the new divisor 212 and the new remainder 77,and apply the division lemma to get

212 = 77 x 2 + 58

We consider the new divisor 77 and the new remainder 58,and apply the division lemma to get

77 = 58 x 1 + 19

We consider the new divisor 58 and the new remainder 19,and apply the division lemma to get

58 = 19 x 3 + 1

We consider the new divisor 19 and the new remainder 1,and apply the division lemma to get

19 = 1 x 19 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 7477 and 1638 is 1

Notice that 1 = HCF(19,1) = HCF(58,19) = HCF(77,58) = HCF(212,77) = HCF(713,212) = HCF(925,713) = HCF(1638,925) = HCF(7477,1638) .

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

Step 1: Since 59390 > 1, we apply the division lemma to 59390 and 1, to get

59390 = 1 x 59390 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 59390 is 1

Notice that 1 = HCF(59390,1) .
