HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 90, 522, 434 i.e. 2 the largest integer that leaves a remainder zero for all numbers.

HCF of 90, 522, 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 90, 522, 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 90, 522, 434 is 2.

HCF(90, 522, 434) = 2

HCF of 90, 522, 434 using Euclid's algorithm

Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.

Highest common factor (HCF) of 90, 522, 434 is 2.

Highest Common Factor of 90,522,434 using Euclid's algorithm

Highest Common Factor of 90,522,434 is 2

Step 1: Since 522 > 90, we apply the division lemma to 522 and 90, to get

522 = 90 x 5 + 72

Step 2: Since the reminder 90 ≠ 0, we apply division lemma to 72 and 90, to get

90 = 72 x 1 + 18

Step 3: We consider the new divisor 72 and the new remainder 18, and apply the division lemma to get

72 = 18 x 4 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 18, the HCF of 90 and 522 is 18

Notice that 18 = HCF(72,18) = HCF(90,72) = HCF(522,90) .


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

Step 1: Since 434 > 18, we apply the division lemma to 434 and 18, to get

434 = 18 x 24 + 2

Step 2: Since the reminder 18 ≠ 0, we apply division lemma to 2 and 18, to get

18 = 2 x 9 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 18 and 434 is 2

Notice that 2 = HCF(18,2) = HCF(434,18) .
