HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 668, 252, 975 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 668, 252, 975 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 668, 252, 975 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 668, 252, 975 is 1.

HCF(668, 252, 975) = 1

Highest common factor (HCF) of 668, 252, 975 is 1.

Highest Common Factor of 668,252,975 using Euclid's algorithm

Highest Common Factor of 668,252,975 is 1

Step 1: Since 668 > 252, we apply the division lemma to 668 and 252, to get

668 = 252 x 2 + 164

Step 2: Since the reminder 252 ≠ 0, we apply division lemma to 164 and 252, to get

252 = 164 x 1 + 88

Step 3: We consider the new divisor 164 and the new remainder 88, and apply the division lemma to get

164 = 88 x 1 + 76

We consider the new divisor 88 and the new remainder 76,and apply the division lemma to get

88 = 76 x 1 + 12

We consider the new divisor 76 and the new remainder 12,and apply the division lemma to get

76 = 12 x 6 + 4

We consider the new divisor 12 and the new remainder 4,and apply the division lemma to get

12 = 4 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 668 and 252 is 4

Notice that 4 = HCF(12,4) = HCF(76,12) = HCF(88,76) = HCF(164,88) = HCF(252,164) = HCF(668,252) .


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

Step 1: Since 975 > 4, we apply the division lemma to 975 and 4, to get

975 = 4 x 243 + 3

Step 2: Since the reminder 4 ≠ 0, we apply division lemma to 3 and 4, to get

4 = 3 x 1 + 1

Step 3: We consider the new divisor 3 and the new remainder 1, and apply the division lemma to get

3 = 1 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 4 and 975 is 1

Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(975,4) .
