HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 818, 321, 155, 984 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 818, 321, 155, 984 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, 321, 155, 984 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, 321, 155, 984 is 1.

HCF(818, 321, 155, 984) = 1

Highest Common Factor of 818,321,155,984 using Euclid's algorithm

Highest Common Factor of 818,321,155,984 is 1

Step 1: Since 818 > 321, we apply the division lemma to 818 and 321, to get

818 = 321 x 2 + 176

Step 2: Since the reminder 321 ≠ 0, we apply division lemma to 176 and 321, to get

321 = 176 x 1 + 145

Step 3: We consider the new divisor 176 and the new remainder 145, and apply the division lemma to get

176 = 145 x 1 + 31

We consider the new divisor 145 and the new remainder 31,and apply the division lemma to get

145 = 31 x 4 + 21

We consider the new divisor 31 and the new remainder 21,and apply the division lemma to get

31 = 21 x 1 + 10

We consider the new divisor 21 and the new remainder 10,and apply the division lemma to get

21 = 10 x 2 + 1

We consider the new divisor 10 and the new remainder 1,and apply the division lemma to get

10 = 1 x 10 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 818 and 321 is 1

Notice that 1 = HCF(10,1) = HCF(21,10) = HCF(31,21) = HCF(145,31) = HCF(176,145) = HCF(321,176) = HCF(818,321) .


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

Step 1: Since 155 > 1, we apply the division lemma to 155 and 1, to get

155 = 1 x 155 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 155 is 1

Notice that 1 = HCF(155,1) .


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

Step 1: Since 984 > 1, we apply the division lemma to 984 and 1, to get

984 = 1 x 984 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 984 is 1

Notice that 1 = HCF(984,1) .
