HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 377, 738, 203, 521 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 377, 738, 203, 521 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 377, 738, 203, 521 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 377, 738, 203, 521 is 1.

HCF(377, 738, 203, 521) = 1

Highest Common Factor of 377,738,203,521 using Euclid's algorithm

Highest Common Factor of 377,738,203,521 is 1

Step 1: Since 738 > 377, we apply the division lemma to 738 and 377, to get

738 = 377 x 1 + 361

Step 2: Since the reminder 377 ≠ 0, we apply division lemma to 361 and 377, to get

377 = 361 x 1 + 16

Step 3: We consider the new divisor 361 and the new remainder 16, and apply the division lemma to get

361 = 16 x 22 + 9

We consider the new divisor 16 and the new remainder 9,and apply the division lemma to get

16 = 9 x 1 + 7

We consider the new divisor 9 and the new remainder 7,and apply the division lemma to get

9 = 7 x 1 + 2

We consider the new divisor 7 and the new remainder 2,and apply the division lemma to get

7 = 2 x 3 + 1

We consider the new divisor 2 and the new remainder 1,and apply the division lemma 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 377 and 738 is 1

Notice that 1 = HCF(2,1) = HCF(7,2) = HCF(9,7) = HCF(16,9) = HCF(361,16) = HCF(377,361) = HCF(738,377) .

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

Step 1: Since 203 > 1, we apply the division lemma to 203 and 1, to get

203 = 1 x 203 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 203 is 1

Notice that 1 = HCF(203,1) .

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

Step 1: Since 521 > 1, we apply the division lemma to 521 and 1, to get

521 = 1 x 521 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 521 is 1

Notice that 1 = HCF(521,1) .
