HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 622, 855, 270 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 622, 855, 270 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 622, 855, 270 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 622, 855, 270 is 1.

HCF(622, 855, 270) = 1

HCF of 622, 855, 270 using Euclid's algorithm

Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.

HCF of:

Highest common factor (HCF) of 622, 855, 270 is 1.

Highest Common Factor of 622,855,270 using Euclid's algorithm

Highest Common Factor of 622,855,270 is 1

Step 1: Since 855 > 622, we apply the division lemma to 855 and 622, to get

855 = 622 x 1 + 233

Step 2: Since the reminder 622 ≠ 0, we apply division lemma to 233 and 622, to get

622 = 233 x 2 + 156

Step 3: We consider the new divisor 233 and the new remainder 156, and apply the division lemma to get

233 = 156 x 1 + 77

We consider the new divisor 156 and the new remainder 77,and apply the division lemma to get

156 = 77 x 2 + 2

We consider the new divisor 77 and the new remainder 2,and apply the division lemma to get

77 = 2 x 38 + 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 622 and 855 is 1

Notice that 1 = HCF(2,1) = HCF(77,2) = HCF(156,77) = HCF(233,156) = HCF(622,233) = HCF(855,622) .

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

Step 1: Since 270 > 1, we apply the division lemma to 270 and 1, to get

270 = 1 x 270 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 270 is 1

Notice that 1 = HCF(270,1) .
