HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 400, 624 i.e. 16 the largest integer that leaves a remainder zero for all numbers.

HCF of 400, 624 is 16 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 400, 624 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 400, 624 is 16.

HCF(400, 624) = 16

HCF of 400, 624 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 400, 624 is 16.

Highest Common Factor of 400,624 using Euclid's algorithm

Highest Common Factor of 400,624 is 16

Step 1: Since 624 > 400, we apply the division lemma to 624 and 400, to get

624 = 400 x 1 + 224

Step 2: Since the reminder 400 ≠ 0, we apply division lemma to 224 and 400, to get

400 = 224 x 1 + 176

Step 3: We consider the new divisor 224 and the new remainder 176, and apply the division lemma to get

224 = 176 x 1 + 48

We consider the new divisor 176 and the new remainder 48,and apply the division lemma to get

176 = 48 x 3 + 32

We consider the new divisor 48 and the new remainder 32,and apply the division lemma to get

48 = 32 x 1 + 16

We consider the new divisor 32 and the new remainder 16,and apply the division lemma to get

32 = 16 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 16, the HCF of 400 and 624 is 16

Notice that 16 = HCF(32,16) = HCF(48,32) = HCF(176,48) = HCF(224,176) = HCF(400,224) = HCF(624,400) .
