HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 557, 688, 77, 166 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 557, 688, 77, 166 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 557, 688, 77, 166 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 557, 688, 77, 166 is 1.

HCF(557, 688, 77, 166) = 1

Highest common factor (HCF) of 557, 688, 77, 166 is 1.

Highest Common Factor of 557,688,77,166 using Euclid's algorithm

Highest Common Factor of 557,688,77,166 is 1

Step 1: Since 688 > 557, we apply the division lemma to 688 and 557, to get

688 = 557 x 1 + 131

Step 2: Since the reminder 557 ≠ 0, we apply division lemma to 131 and 557, to get

557 = 131 x 4 + 33

Step 3: We consider the new divisor 131 and the new remainder 33, and apply the division lemma to get

131 = 33 x 3 + 32

We consider the new divisor 33 and the new remainder 32,and apply the division lemma to get

33 = 32 x 1 + 1

We consider the new divisor 32 and the new remainder 1,and apply the division lemma to get

32 = 1 x 32 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 557 and 688 is 1

Notice that 1 = HCF(32,1) = HCF(33,32) = HCF(131,33) = HCF(557,131) = HCF(688,557) .


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

Step 1: Since 77 > 1, we apply the division lemma to 77 and 1, to get

77 = 1 x 77 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 77 is 1

Notice that 1 = HCF(77,1) .


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

Step 1: Since 166 > 1, we apply the division lemma to 166 and 1, to get

166 = 1 x 166 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 166 is 1

Notice that 1 = HCF(166,1) .
