HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 42, 94, 74, 434 i.e. 2 the largest integer that leaves a remainder zero for all numbers.

HCF of 42, 94, 74, 434 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 42, 94, 74, 434 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 42, 94, 74, 434 is 2.

HCF(42, 94, 74, 434) = 2

## HCF of 42, 94, 74, 434 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 42, 94, 74, 434 is 2. ### Highest Common Factor of 42,94,74,434 is 2

Step 1: Since 94 > 42, we apply the division lemma to 94 and 42, to get

94 = 42 x 2 + 10

Step 2: Since the reminder 42 ≠ 0, we apply division lemma to 10 and 42, to get

42 = 10 x 4 + 2

Step 3: We consider the new divisor 10 and the new remainder 2, and apply the division lemma to get

10 = 2 x 5 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 42 and 94 is 2

Notice that 2 = HCF(10,2) = HCF(42,10) = HCF(94,42) .

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

Step 1: Since 74 > 2, we apply the division lemma to 74 and 2, to get

74 = 2 x 37 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 74 is 2

Notice that 2 = HCF(74,2) .

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

Step 1: Since 434 > 2, we apply the division lemma to 434 and 2, to get

434 = 2 x 217 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 434 is 2

Notice that 2 = HCF(434,2) .
