HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 284, 442, 343, 620 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 284, 442, 343, 620 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 284, 442, 343, 620 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 284, 442, 343, 620 is 1.

HCF(284, 442, 343, 620) = 1

Highest Common Factor of 284,442,343,620 using Euclid's algorithm

Highest Common Factor of 284,442,343,620 is 1

Step 1: Since 442 > 284, we apply the division lemma to 442 and 284, to get

442 = 284 x 1 + 158

Step 2: Since the reminder 284 ≠ 0, we apply division lemma to 158 and 284, to get

284 = 158 x 1 + 126

Step 3: We consider the new divisor 158 and the new remainder 126, and apply the division lemma to get

158 = 126 x 1 + 32

We consider the new divisor 126 and the new remainder 32,and apply the division lemma to get

126 = 32 x 3 + 30

We consider the new divisor 32 and the new remainder 30,and apply the division lemma to get

32 = 30 x 1 + 2

We consider the new divisor 30 and the new remainder 2,and apply the division lemma to get

30 = 2 x 15 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 284 and 442 is 2

Notice that 2 = HCF(30,2) = HCF(32,30) = HCF(126,32) = HCF(158,126) = HCF(284,158) = HCF(442,284) .


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

Step 1: Since 343 > 2, we apply the division lemma to 343 and 2, to get

343 = 2 x 171 + 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 343 is 1

Notice that 1 = HCF(2,1) = HCF(343,2) .


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

Step 1: Since 620 > 1, we apply the division lemma to 620 and 1, to get

620 = 1 x 620 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 620 is 1

Notice that 1 = HCF(620,1) .
