HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 818, 789, 22, 930 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 818, 789, 22, 930 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 818, 789, 22, 930 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 818, 789, 22, 930 is 1.

HCF(818, 789, 22, 930) = 1

Highest common factor (HCF) of 818, 789, 22, 930 is 1.

Highest Common Factor of 818,789,22,930 using Euclid's algorithm

Highest Common Factor of 818,789,22,930 is 1

Step 1: Since 818 > 789, we apply the division lemma to 818 and 789, to get

818 = 789 x 1 + 29

Step 2: Since the reminder 789 ≠ 0, we apply division lemma to 29 and 789, to get

789 = 29 x 27 + 6

Step 3: We consider the new divisor 29 and the new remainder 6, and apply the division lemma to get

29 = 6 x 4 + 5

We consider the new divisor 6 and the new remainder 5,and apply the division lemma to get

6 = 5 x 1 + 1

We consider the new divisor 5 and the new remainder 1,and apply the division lemma to get

5 = 1 x 5 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 818 and 789 is 1

Notice that 1 = HCF(5,1) = HCF(6,5) = HCF(29,6) = HCF(789,29) = HCF(818,789) .


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

Step 1: Since 22 > 1, we apply the division lemma to 22 and 1, to get

22 = 1 x 22 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 22 is 1

Notice that 1 = HCF(22,1) .


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

Step 1: Since 930 > 1, we apply the division lemma to 930 and 1, to get

930 = 1 x 930 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 930 is 1

Notice that 1 = HCF(930,1) .
