HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 428, 901, 166 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 428, 901, 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 428, 901, 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 428, 901, 166 is 1.

HCF(428, 901, 166) = 1

HCF of 428, 901, 166 using Euclid's algorithm

Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.

HCF of:

Highest common factor (HCF) of 428, 901, 166 is 1.

Highest Common Factor of 428,901,166 using Euclid's algorithm

Highest Common Factor of 428,901,166 is 1

Step 1: Since 901 > 428, we apply the division lemma to 901 and 428, to get

901 = 428 x 2 + 45

Step 2: Since the reminder 428 ≠ 0, we apply division lemma to 45 and 428, to get

428 = 45 x 9 + 23

Step 3: We consider the new divisor 45 and the new remainder 23, and apply the division lemma to get

45 = 23 x 1 + 22

We consider the new divisor 23 and the new remainder 22,and apply the division lemma to get

23 = 22 x 1 + 1

We consider the new divisor 22 and the new remainder 1,and apply the division lemma to get

22 = 1 x 22 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 428 and 901 is 1

Notice that 1 = HCF(22,1) = HCF(23,22) = HCF(45,23) = HCF(428,45) = HCF(901,428) .


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) .
