HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 243, 371, 850 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 243, 371, 850 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 243, 371, 850 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 243, 371, 850 is 1.

HCF(243, 371, 850) = 1

Highest common factor (HCF) of 243, 371, 850 is 1.

Highest Common Factor of 243,371,850 using Euclid's algorithm

Highest Common Factor of 243,371,850 is 1

Step 1: Since 371 > 243, we apply the division lemma to 371 and 243, to get

371 = 243 x 1 + 128

Step 2: Since the reminder 243 ≠ 0, we apply division lemma to 128 and 243, to get

243 = 128 x 1 + 115

Step 3: We consider the new divisor 128 and the new remainder 115, and apply the division lemma to get

128 = 115 x 1 + 13

We consider the new divisor 115 and the new remainder 13,and apply the division lemma to get

115 = 13 x 8 + 11

We consider the new divisor 13 and the new remainder 11,and apply the division lemma to get

13 = 11 x 1 + 2

We consider the new divisor 11 and the new remainder 2,and apply the division lemma to get

11 = 2 x 5 + 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 243 and 371 is 1

Notice that 1 = HCF(2,1) = HCF(11,2) = HCF(13,11) = HCF(115,13) = HCF(128,115) = HCF(243,128) = HCF(371,243) .

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

Step 1: Since 850 > 1, we apply the division lemma to 850 and 1, to get

850 = 1 x 850 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 850 is 1

Notice that 1 = HCF(850,1) .
