HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 694, 542, 629 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 694, 542, 629 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 694, 542, 629 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 694, 542, 629 is 1.

HCF(694, 542, 629) = 1

Highest common factor (HCF) of 694, 542, 629 is 1.

Highest Common Factor of 694,542,629 using Euclid's algorithm

Highest Common Factor of 694,542,629 is 1

Step 1: Since 694 > 542, we apply the division lemma to 694 and 542, to get

694 = 542 x 1 + 152

Step 2: Since the reminder 542 ≠ 0, we apply division lemma to 152 and 542, to get

542 = 152 x 3 + 86

Step 3: We consider the new divisor 152 and the new remainder 86, and apply the division lemma to get

152 = 86 x 1 + 66

We consider the new divisor 86 and the new remainder 66,and apply the division lemma to get

86 = 66 x 1 + 20

We consider the new divisor 66 and the new remainder 20,and apply the division lemma to get

66 = 20 x 3 + 6

We consider the new divisor 20 and the new remainder 6,and apply the division lemma to get

20 = 6 x 3 + 2

We consider the new divisor 6 and the new remainder 2,and apply the division lemma to get

6 = 2 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 694 and 542 is 2

Notice that 2 = HCF(6,2) = HCF(20,6) = HCF(66,20) = HCF(86,66) = HCF(152,86) = HCF(542,152) = HCF(694,542) .

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

Step 1: Since 629 > 2, we apply the division lemma to 629 and 2, to get

629 = 2 x 314 + 1

Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, 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 2 and 629 is 1

Notice that 1 = HCF(2,1) = HCF(629,2) .
