HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 807, 637, 550 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 807, 637, 550 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 807, 637, 550 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 807, 637, 550 is 1.

HCF(807, 637, 550) = 1

Highest common factor (HCF) of 807, 637, 550 is 1.

Highest Common Factor of 807,637,550 using Euclid's algorithm

Highest Common Factor of 807,637,550 is 1

Step 1: Since 807 > 637, we apply the division lemma to 807 and 637, to get

807 = 637 x 1 + 170

Step 2: Since the reminder 637 ≠ 0, we apply division lemma to 170 and 637, to get

637 = 170 x 3 + 127

Step 3: We consider the new divisor 170 and the new remainder 127, and apply the division lemma to get

170 = 127 x 1 + 43

We consider the new divisor 127 and the new remainder 43,and apply the division lemma to get

127 = 43 x 2 + 41

We consider the new divisor 43 and the new remainder 41,and apply the division lemma to get

43 = 41 x 1 + 2

We consider the new divisor 41 and the new remainder 2,and apply the division lemma to get

41 = 2 x 20 + 1

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 807 and 637 is 1

Notice that 1 = HCF(2,1) = HCF(41,2) = HCF(43,41) = HCF(127,43) = HCF(170,127) = HCF(637,170) = HCF(807,637) .

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

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

550 = 1 x 550 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 550 is 1

Notice that 1 = HCF(550,1) .
