HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 190, 492, 177 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 190, 492, 177 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 190, 492, 177 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 190, 492, 177 is 1.

HCF(190, 492, 177) = 1

Highest common factor (HCF) of 190, 492, 177 is 1.

Highest Common Factor of 190,492,177 using Euclid's algorithm

Highest Common Factor of 190,492,177 is 1

Step 1: Since 492 > 190, we apply the division lemma to 492 and 190, to get

492 = 190 x 2 + 112

Step 2: Since the reminder 190 ≠ 0, we apply division lemma to 112 and 190, to get

190 = 112 x 1 + 78

Step 3: We consider the new divisor 112 and the new remainder 78, and apply the division lemma to get

112 = 78 x 1 + 34

We consider the new divisor 78 and the new remainder 34,and apply the division lemma to get

78 = 34 x 2 + 10

We consider the new divisor 34 and the new remainder 10,and apply the division lemma to get

34 = 10 x 3 + 4

We consider the new divisor 10 and the new remainder 4,and apply the division lemma to get

10 = 4 x 2 + 2

We consider the new divisor 4 and the new remainder 2,and apply the division lemma to get

4 = 2 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 190 and 492 is 2

Notice that 2 = HCF(4,2) = HCF(10,4) = HCF(34,10) = HCF(78,34) = HCF(112,78) = HCF(190,112) = HCF(492,190) .

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

Step 1: Since 177 > 2, we apply the division lemma to 177 and 2, to get

177 = 2 x 88 + 1

Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, to get

2 = 1 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 2 and 177 is 1

Notice that 1 = HCF(2,1) = HCF(177,2) .
