HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 621, 893, 689, 178 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 621, 893, 689, 178 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 621, 893, 689, 178 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 621, 893, 689, 178 is 1.

HCF(621, 893, 689, 178) = 1

Highest common factor (HCF) of 621, 893, 689, 178 is 1.

Highest Common Factor of 621,893,689,178 using Euclid's algorithm

Highest Common Factor of 621,893,689,178 is 1

Step 1: Since 893 > 621, we apply the division lemma to 893 and 621, to get

893 = 621 x 1 + 272

Step 2: Since the reminder 621 ≠ 0, we apply division lemma to 272 and 621, to get

621 = 272 x 2 + 77

Step 3: We consider the new divisor 272 and the new remainder 77, and apply the division lemma to get

272 = 77 x 3 + 41

We consider the new divisor 77 and the new remainder 41,and apply the division lemma to get

77 = 41 x 1 + 36

We consider the new divisor 41 and the new remainder 36,and apply the division lemma to get

41 = 36 x 1 + 5

We consider the new divisor 36 and the new remainder 5,and apply the division lemma to get

36 = 5 x 7 + 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 621 and 893 is 1

Notice that 1 = HCF(5,1) = HCF(36,5) = HCF(41,36) = HCF(77,41) = HCF(272,77) = HCF(621,272) = HCF(893,621) .


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

Step 1: Since 689 > 1, we apply the division lemma to 689 and 1, to get

689 = 1 x 689 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 689 is 1

Notice that 1 = HCF(689,1) .


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

Step 1: Since 178 > 1, we apply the division lemma to 178 and 1, to get

178 = 1 x 178 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 178 is 1

Notice that 1 = HCF(178,1) .
