HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 649, 825, 33 i.e. 11 the largest integer that leaves a remainder zero for all numbers.

HCF of 649, 825, 33 is 11 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 649, 825, 33 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 649, 825, 33 is 11.

HCF(649, 825, 33) = 11

Highest common factor (HCF) of 649, 825, 33 is 11.

Highest Common Factor of 649,825,33 using Euclid's algorithm

Highest Common Factor of 649,825,33 is 11

Step 1: Since 825 > 649, we apply the division lemma to 825 and 649, to get

825 = 649 x 1 + 176

Step 2: Since the reminder 649 ≠ 0, we apply division lemma to 176 and 649, to get

649 = 176 x 3 + 121

Step 3: We consider the new divisor 176 and the new remainder 121, and apply the division lemma to get

176 = 121 x 1 + 55

We consider the new divisor 121 and the new remainder 55,and apply the division lemma to get

121 = 55 x 2 + 11

We consider the new divisor 55 and the new remainder 11,and apply the division lemma to get

55 = 11 x 5 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 11, the HCF of 649 and 825 is 11

Notice that 11 = HCF(55,11) = HCF(121,55) = HCF(176,121) = HCF(649,176) = HCF(825,649) .


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

Step 1: Since 33 > 11, we apply the division lemma to 33 and 11, to get

33 = 11 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 11, the HCF of 11 and 33 is 11

Notice that 11 = HCF(33,11) .
