HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 155, 402, 877 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 155, 402, 877 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 155, 402, 877 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 155, 402, 877 is 1.

HCF(155, 402, 877) = 1

Highest common factor (HCF) of 155, 402, 877 is 1.

Highest Common Factor of 155,402,877 using Euclid's algorithm

Highest Common Factor of 155,402,877 is 1

Step 1: Since 402 > 155, we apply the division lemma to 402 and 155, to get

402 = 155 x 2 + 92

Step 2: Since the reminder 155 ≠ 0, we apply division lemma to 92 and 155, to get

155 = 92 x 1 + 63

Step 3: We consider the new divisor 92 and the new remainder 63, and apply the division lemma to get

92 = 63 x 1 + 29

We consider the new divisor 63 and the new remainder 29,and apply the division lemma to get

63 = 29 x 2 + 5

We consider the new divisor 29 and the new remainder 5,and apply the division lemma to get

29 = 5 x 5 + 4

We consider the new divisor 5 and the new remainder 4,and apply the division lemma to get

5 = 4 x 1 + 1

We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get

4 = 1 x 4 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 155 and 402 is 1

Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(29,5) = HCF(63,29) = HCF(92,63) = HCF(155,92) = HCF(402,155) .


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

Step 1: Since 877 > 1, we apply the division lemma to 877 and 1, to get

877 = 1 x 877 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 877 is 1

Notice that 1 = HCF(877,1) .
