HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 273, 428, 400, 302 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 273, 428, 400, 302 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 273, 428, 400, 302 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 273, 428, 400, 302 is 1.

HCF(273, 428, 400, 302) = 1

Highest Common Factor of 273,428,400,302 using Euclid's algorithm

Highest Common Factor of 273,428,400,302 is 1

Step 1: Since 428 > 273, we apply the division lemma to 428 and 273, to get

428 = 273 x 1 + 155

Step 2: Since the reminder 273 ≠ 0, we apply division lemma to 155 and 273, to get

273 = 155 x 1 + 118

Step 3: We consider the new divisor 155 and the new remainder 118, and apply the division lemma to get

155 = 118 x 1 + 37

We consider the new divisor 118 and the new remainder 37,and apply the division lemma to get

118 = 37 x 3 + 7

We consider the new divisor 37 and the new remainder 7,and apply the division lemma to get

37 = 7 x 5 + 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 273 and 428 is 1

Notice that 1 = HCF(2,1) = HCF(7,2) = HCF(37,7) = HCF(118,37) = HCF(155,118) = HCF(273,155) = HCF(428,273) .


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

Step 1: Since 400 > 1, we apply the division lemma to 400 and 1, to get

400 = 1 x 400 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 400 is 1

Notice that 1 = HCF(400,1) .


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

Step 1: Since 302 > 1, we apply the division lemma to 302 and 1, to get

302 = 1 x 302 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 302 is 1

Notice that 1 = HCF(302,1) .
