HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 812, 502, 153 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 812, 502, 153 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 812, 502, 153 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 812, 502, 153 is 1.

HCF(812, 502, 153) = 1

Highest Common Factor of 812,502,153 using Euclid's algorithm

Highest Common Factor of 812,502,153 is 1

Step 1: Since 812 > 502, we apply the division lemma to 812 and 502, to get

812 = 502 x 1 + 310

Step 2: Since the reminder 502 ≠ 0, we apply division lemma to 310 and 502, to get

502 = 310 x 1 + 192

Step 3: We consider the new divisor 310 and the new remainder 192, and apply the division lemma to get

310 = 192 x 1 + 118

We consider the new divisor 192 and the new remainder 118,and apply the division lemma to get

192 = 118 x 1 + 74

We consider the new divisor 118 and the new remainder 74,and apply the division lemma to get

118 = 74 x 1 + 44

We consider the new divisor 74 and the new remainder 44,and apply the division lemma to get

74 = 44 x 1 + 30

We consider the new divisor 44 and the new remainder 30,and apply the division lemma to get

44 = 30 x 1 + 14

We consider the new divisor 30 and the new remainder 14,and apply the division lemma to get

30 = 14 x 2 + 2

We consider the new divisor 14 and the new remainder 2,and apply the division lemma to get

14 = 2 x 7 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 812 and 502 is 2

Notice that 2 = HCF(14,2) = HCF(30,14) = HCF(44,30) = HCF(74,44) = HCF(118,74) = HCF(192,118) = HCF(310,192) = HCF(502,310) = HCF(812,502) .

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

Step 1: Since 153 > 2, we apply the division lemma to 153 and 2, to get

153 = 2 x 76 + 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 153 is 1

Notice that 1 = HCF(2,1) = HCF(153,2) .
