HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 642, 883, 281 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 642, 883, 281 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 642, 883, 281 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 642, 883, 281 is 1.

HCF(642, 883, 281) = 1

Highest common factor (HCF) of 642, 883, 281 is 1.

Highest Common Factor of 642,883,281 using Euclid's algorithm

Highest Common Factor of 642,883,281 is 1

Step 1: Since 883 > 642, we apply the division lemma to 883 and 642, to get

883 = 642 x 1 + 241

Step 2: Since the reminder 642 ≠ 0, we apply division lemma to 241 and 642, to get

642 = 241 x 2 + 160

Step 3: We consider the new divisor 241 and the new remainder 160, and apply the division lemma to get

241 = 160 x 1 + 81

We consider the new divisor 160 and the new remainder 81,and apply the division lemma to get

160 = 81 x 1 + 79

We consider the new divisor 81 and the new remainder 79,and apply the division lemma to get

81 = 79 x 1 + 2

We consider the new divisor 79 and the new remainder 2,and apply the division lemma to get

79 = 2 x 39 + 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 642 and 883 is 1

Notice that 1 = HCF(2,1) = HCF(79,2) = HCF(81,79) = HCF(160,81) = HCF(241,160) = HCF(642,241) = HCF(883,642) .

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

Step 1: Since 281 > 1, we apply the division lemma to 281 and 1, to get

281 = 1 x 281 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 281 is 1

Notice that 1 = HCF(281,1) .
