HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 840, 533, 228 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 840, 533, 228 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 840, 533, 228 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 840, 533, 228 is 1.

HCF(840, 533, 228) = 1

Highest common factor (HCF) of 840, 533, 228 is 1.

Highest Common Factor of 840,533,228 using Euclid's algorithm

Highest Common Factor of 840,533,228 is 1

Step 1: Since 840 > 533, we apply the division lemma to 840 and 533, to get

840 = 533 x 1 + 307

Step 2: Since the reminder 533 ≠ 0, we apply division lemma to 307 and 533, to get

533 = 307 x 1 + 226

Step 3: We consider the new divisor 307 and the new remainder 226, and apply the division lemma to get

307 = 226 x 1 + 81

We consider the new divisor 226 and the new remainder 81,and apply the division lemma to get

226 = 81 x 2 + 64

We consider the new divisor 81 and the new remainder 64,and apply the division lemma to get

81 = 64 x 1 + 17

We consider the new divisor 64 and the new remainder 17,and apply the division lemma to get

64 = 17 x 3 + 13

We consider the new divisor 17 and the new remainder 13,and apply the division lemma to get

17 = 13 x 1 + 4

We consider the new divisor 13 and the new remainder 4,and apply the division lemma to get

13 = 4 x 3 + 1

We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get

4 = 1 x 4 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 840 and 533 is 1

Notice that 1 = HCF(4,1) = HCF(13,4) = HCF(17,13) = HCF(64,17) = HCF(81,64) = HCF(226,81) = HCF(307,226) = HCF(533,307) = HCF(840,533) .


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

Step 1: Since 228 > 1, we apply the division lemma to 228 and 1, to get

228 = 1 x 228 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 228 is 1

Notice that 1 = HCF(228,1) .
