HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 408, 765 i.e. 51 the largest integer that leaves a remainder zero for all numbers.

HCF of 408, 765 is 51 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 408, 765 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 408, 765 is 51.

HCF(408, 765) = 51

Highest common factor (HCF) of 408, 765 is 51.

Highest Common Factor of 408,765 using Euclid's algorithm

Highest Common Factor of 408,765 is 51

Step 1: Since 765 > 408, we apply the division lemma to 765 and 408, to get

765 = 408 x 1 + 357

Step 2: Since the reminder 408 ≠ 0, we apply division lemma to 357 and 408, to get

408 = 357 x 1 + 51

Step 3: We consider the new divisor 357 and the new remainder 51, and apply the division lemma to get

357 = 51 x 7 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 51, the HCF of 408 and 765 is 51

Notice that 51 = HCF(357,51) = HCF(408,357) = HCF(765,408) .
