HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 734, 946, 21 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 734, 946, 21 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 734, 946, 21 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 734, 946, 21 is 1.

HCF(734, 946, 21) = 1

HCF of 734, 946, 21 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 734, 946, 21 is 1.

Highest Common Factor of 734,946,21 using Euclid's algorithm

Highest Common Factor of 734,946,21 is 1

Step 1: Since 946 > 734, we apply the division lemma to 946 and 734, to get

946 = 734 x 1 + 212

Step 2: Since the reminder 734 ≠ 0, we apply division lemma to 212 and 734, to get

734 = 212 x 3 + 98

Step 3: We consider the new divisor 212 and the new remainder 98, and apply the division lemma to get

212 = 98 x 2 + 16

We consider the new divisor 98 and the new remainder 16,and apply the division lemma to get

98 = 16 x 6 + 2

We consider the new divisor 16 and the new remainder 2,and apply the division lemma to get

16 = 2 x 8 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 734 and 946 is 2

Notice that 2 = HCF(16,2) = HCF(98,16) = HCF(212,98) = HCF(734,212) = HCF(946,734) .


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

Step 1: Since 21 > 2, we apply the division lemma to 21 and 2, to get

21 = 2 x 10 + 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 21 is 1

Notice that 1 = HCF(2,1) = HCF(21,2) .
