HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 128, 504 i.e. 8 the largest integer that leaves a remainder zero for all numbers.

HCF of 128, 504 is 8 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 128, 504 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 128, 504 is 8.

HCF(128, 504) = 8

HCF of 128, 504 using Euclid's algorithm

Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.

HCF of:

Highest common factor (HCF) of 128, 504 is 8.

Highest Common Factor of 128,504 using Euclid's algorithm

Highest Common Factor of 128,504 is 8

Step 1: Since 504 > 128, we apply the division lemma to 504 and 128, to get

504 = 128 x 3 + 120

Step 2: Since the reminder 128 ≠ 0, we apply division lemma to 120 and 128, to get

128 = 120 x 1 + 8

Step 3: We consider the new divisor 120 and the new remainder 8, and apply the division lemma to get

120 = 8 x 15 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 8, the HCF of 128 and 504 is 8

Notice that 8 = HCF(120,8) = HCF(128,120) = HCF(504,128) .
