HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 542, 430, 195 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 542, 430, 195 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 542, 430, 195 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 542, 430, 195 is 1.

HCF(542, 430, 195) = 1

Highest common factor (HCF) of 542, 430, 195 is 1.

Highest Common Factor of 542,430,195 using Euclid's algorithm

Highest Common Factor of 542,430,195 is 1

Step 1: Since 542 > 430, we apply the division lemma to 542 and 430, to get

542 = 430 x 1 + 112

Step 2: Since the reminder 430 ≠ 0, we apply division lemma to 112 and 430, to get

430 = 112 x 3 + 94

Step 3: We consider the new divisor 112 and the new remainder 94, and apply the division lemma to get

112 = 94 x 1 + 18

We consider the new divisor 94 and the new remainder 18,and apply the division lemma to get

94 = 18 x 5 + 4

We consider the new divisor 18 and the new remainder 4,and apply the division lemma to get

18 = 4 x 4 + 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 542 and 430 is 2

Notice that 2 = HCF(4,2) = HCF(18,4) = HCF(94,18) = HCF(112,94) = HCF(430,112) = HCF(542,430) .

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

Step 1: Since 195 > 2, we apply the division lemma to 195 and 2, to get

195 = 2 x 97 + 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 195 is 1

Notice that 1 = HCF(2,1) = HCF(195,2) .
