HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 675, 990 i.e. 45 the largest integer that leaves a remainder zero for all numbers.

HCF of 675, 990 is 45 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 675, 990 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 675, 990 is 45.

HCF(675, 990) = 45

Highest common factor (HCF) of 675, 990 is 45.

Highest Common Factor of 675,990 using Euclid's algorithm

Highest Common Factor of 675,990 is 45

Step 1: Since 990 > 675, we apply the division lemma to 990 and 675, to get

990 = 675 x 1 + 315

Step 2: Since the reminder 675 ≠ 0, we apply division lemma to 315 and 675, to get

675 = 315 x 2 + 45

Step 3: We consider the new divisor 315 and the new remainder 45, and apply the division lemma to get

315 = 45 x 7 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 45, the HCF of 675 and 990 is 45

Notice that 45 = HCF(315,45) = HCF(675,315) = HCF(990,675) .
