HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 351, 520, 820, 162 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 351, 520, 820, 162 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 351, 520, 820, 162 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 351, 520, 820, 162 is 1.

HCF(351, 520, 820, 162) = 1

Highest common factor (HCF) of 351, 520, 820, 162 is 1.

Highest Common Factor of 351,520,820,162 using Euclid's algorithm

Highest Common Factor of 351,520,820,162 is 1

Step 1: Since 520 > 351, we apply the division lemma to 520 and 351, to get

520 = 351 x 1 + 169

Step 2: Since the reminder 351 ≠ 0, we apply division lemma to 169 and 351, to get

351 = 169 x 2 + 13

Step 3: We consider the new divisor 169 and the new remainder 13, and apply the division lemma to get

169 = 13 x 13 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 13, the HCF of 351 and 520 is 13

Notice that 13 = HCF(169,13) = HCF(351,169) = HCF(520,351) .


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

Step 1: Since 820 > 13, we apply the division lemma to 820 and 13, to get

820 = 13 x 63 + 1

Step 2: Since the reminder 13 ≠ 0, we apply division lemma to 1 and 13, to get

13 = 1 x 13 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 13 and 820 is 1

Notice that 1 = HCF(13,1) = HCF(820,13) .


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

Step 1: Since 162 > 1, we apply the division lemma to 162 and 1, to get

162 = 1 x 162 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 162 is 1

Notice that 1 = HCF(162,1) .
