HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 965, 402, 555 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 965, 402, 555 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 965, 402, 555 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 965, 402, 555 is 1.

HCF(965, 402, 555) = 1

HCF of 965, 402, 555 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 965, 402, 555 is 1.

Highest Common Factor of 965,402,555 using Euclid's algorithm

Highest Common Factor of 965,402,555 is 1

Step 1: Since 965 > 402, we apply the division lemma to 965 and 402, to get

965 = 402 x 2 + 161

Step 2: Since the reminder 402 ≠ 0, we apply division lemma to 161 and 402, to get

402 = 161 x 2 + 80

Step 3: We consider the new divisor 161 and the new remainder 80, and apply the division lemma to get

161 = 80 x 2 + 1

We consider the new divisor 80 and the new remainder 1, and apply the division lemma to get

80 = 1 x 80 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 965 and 402 is 1

Notice that 1 = HCF(80,1) = HCF(161,80) = HCF(402,161) = HCF(965,402) .


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

Step 1: Since 555 > 1, we apply the division lemma to 555 and 1, to get

555 = 1 x 555 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 555 is 1

Notice that 1 = HCF(555,1) .
