HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 857, 1563, 1449 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 857, 1563, 1449 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 857, 1563, 1449 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 857, 1563, 1449 is 1.

HCF(857, 1563, 1449) = 1

Highest common factor (HCF) of 857, 1563, 1449 is 1.

Highest Common Factor of 857,1563,1449 using Euclid's algorithm

Highest Common Factor of 857,1563,1449 is 1

Step 1: Since 1563 > 857, we apply the division lemma to 1563 and 857, to get

1563 = 857 x 1 + 706

Step 2: Since the reminder 857 ≠ 0, we apply division lemma to 706 and 857, to get

857 = 706 x 1 + 151

Step 3: We consider the new divisor 706 and the new remainder 151, and apply the division lemma to get

706 = 151 x 4 + 102

We consider the new divisor 151 and the new remainder 102,and apply the division lemma to get

151 = 102 x 1 + 49

We consider the new divisor 102 and the new remainder 49,and apply the division lemma to get

102 = 49 x 2 + 4

We consider the new divisor 49 and the new remainder 4,and apply the division lemma to get

49 = 4 x 12 + 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 857 and 1563 is 1

Notice that 1 = HCF(4,1) = HCF(49,4) = HCF(102,49) = HCF(151,102) = HCF(706,151) = HCF(857,706) = HCF(1563,857) .


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

Step 1: Since 1449 > 1, we apply the division lemma to 1449 and 1, to get

1449 = 1 x 1449 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 1449 is 1

Notice that 1 = HCF(1449,1) .
