HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 199, 728, 804, 378 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 199, 728, 804, 378 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 199, 728, 804, 378 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 199, 728, 804, 378 is 1.

HCF(199, 728, 804, 378) = 1

Highest Common Factor of 199,728,804,378 using Euclid's algorithm

Highest Common Factor of 199,728,804,378 is 1

Step 1: Since 728 > 199, we apply the division lemma to 728 and 199, to get

728 = 199 x 3 + 131

Step 2: Since the reminder 199 ≠ 0, we apply division lemma to 131 and 199, to get

199 = 131 x 1 + 68

Step 3: We consider the new divisor 131 and the new remainder 68, and apply the division lemma to get

131 = 68 x 1 + 63

We consider the new divisor 68 and the new remainder 63,and apply the division lemma to get

68 = 63 x 1 + 5

We consider the new divisor 63 and the new remainder 5,and apply the division lemma to get

63 = 5 x 12 + 3

We consider the new divisor 5 and the new remainder 3,and apply the division lemma to get

5 = 3 x 1 + 2

We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get

3 = 2 x 1 + 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 199 and 728 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(63,5) = HCF(68,63) = HCF(131,68) = HCF(199,131) = HCF(728,199) .


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

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

804 = 1 x 804 + 0

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

Notice that 1 = HCF(804,1) .


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

Step 1: Since 378 > 1, we apply the division lemma to 378 and 1, to get

378 = 1 x 378 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 378 is 1

Notice that 1 = HCF(378,1) .
