HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 623, 552, 642 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 623, 552, 642 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 623, 552, 642 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 623, 552, 642 is 1.

HCF(623, 552, 642) = 1

Highest common factor (HCF) of 623, 552, 642 is 1.

Highest Common Factor of 623,552,642 using Euclid's algorithm

Highest Common Factor of 623,552,642 is 1

Step 1: Since 623 > 552, we apply the division lemma to 623 and 552, to get

623 = 552 x 1 + 71

Step 2: Since the reminder 552 ≠ 0, we apply division lemma to 71 and 552, to get

552 = 71 x 7 + 55

Step 3: We consider the new divisor 71 and the new remainder 55, and apply the division lemma to get

71 = 55 x 1 + 16

We consider the new divisor 55 and the new remainder 16,and apply the division lemma to get

55 = 16 x 3 + 7

We consider the new divisor 16 and the new remainder 7,and apply the division lemma to get

16 = 7 x 2 + 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 623 and 552 is 1

Notice that 1 = HCF(2,1) = HCF(7,2) = HCF(16,7) = HCF(55,16) = HCF(71,55) = HCF(552,71) = HCF(623,552) .

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

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

642 = 1 x 642 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 642 is 1

Notice that 1 = HCF(642,1) .
