HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 234, 142, 30 i.e. 2 the largest integer that leaves a remainder zero for all numbers.

HCF of 234, 142, 30 is 2 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 234, 142, 30 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 234, 142, 30 is 2.

HCF(234, 142, 30) = 2

Highest Common Factor of 234,142,30 using Euclid's algorithm

Highest Common Factor of 234,142,30 is 2

Step 1: Since 234 > 142, we apply the division lemma to 234 and 142, to get

234 = 142 x 1 + 92

Step 2: Since the reminder 142 ≠ 0, we apply division lemma to 92 and 142, to get

142 = 92 x 1 + 50

Step 3: We consider the new divisor 92 and the new remainder 50, and apply the division lemma to get

92 = 50 x 1 + 42

We consider the new divisor 50 and the new remainder 42,and apply the division lemma to get

50 = 42 x 1 + 8

We consider the new divisor 42 and the new remainder 8,and apply the division lemma to get

42 = 8 x 5 + 2

We consider the new divisor 8 and the new remainder 2,and apply the division lemma to get

8 = 2 x 4 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 234 and 142 is 2

Notice that 2 = HCF(8,2) = HCF(42,8) = HCF(50,42) = HCF(92,50) = HCF(142,92) = HCF(234,142) .


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

Step 1: Since 30 > 2, we apply the division lemma to 30 and 2, to get

30 = 2 x 15 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 30 is 2

Notice that 2 = HCF(30,2) .
