HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 407, 550, 244 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 407, 550, 244 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 407, 550, 244 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 407, 550, 244 is 1.

HCF(407, 550, 244) = 1

Highest Common Factor of 407,550,244 using Euclid's algorithm

Highest Common Factor of 407,550,244 is 1

Step 1: Since 550 > 407, we apply the division lemma to 550 and 407, to get

550 = 407 x 1 + 143

Step 2: Since the reminder 407 ≠ 0, we apply division lemma to 143 and 407, to get

407 = 143 x 2 + 121

Step 3: We consider the new divisor 143 and the new remainder 121, and apply the division lemma to get

143 = 121 x 1 + 22

We consider the new divisor 121 and the new remainder 22,and apply the division lemma to get

121 = 22 x 5 + 11

We consider the new divisor 22 and the new remainder 11,and apply the division lemma to get

22 = 11 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 11, the HCF of 407 and 550 is 11

Notice that 11 = HCF(22,11) = HCF(121,22) = HCF(143,121) = HCF(407,143) = HCF(550,407) .

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

Step 1: Since 244 > 11, we apply the division lemma to 244 and 11, to get

244 = 11 x 22 + 2

Step 2: Since the reminder 11 ≠ 0, we apply division lemma to 2 and 11, to get

11 = 2 x 5 + 1

Step 3: We consider the new divisor 2 and the new remainder 1, and apply the division lemma 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 11 and 244 is 1

Notice that 1 = HCF(2,1) = HCF(11,2) = HCF(244,11) .
