HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 639, 995, 392, 223 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 639, 995, 392, 223 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 639, 995, 392, 223 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 639, 995, 392, 223 is 1.

HCF(639, 995, 392, 223) = 1

Highest common factor (HCF) of 639, 995, 392, 223 is 1.

Highest Common Factor of 639,995,392,223 using Euclid's algorithm

Highest Common Factor of 639,995,392,223 is 1

Step 1: Since 995 > 639, we apply the division lemma to 995 and 639, to get

995 = 639 x 1 + 356

Step 2: Since the reminder 639 ≠ 0, we apply division lemma to 356 and 639, to get

639 = 356 x 1 + 283

Step 3: We consider the new divisor 356 and the new remainder 283, and apply the division lemma to get

356 = 283 x 1 + 73

We consider the new divisor 283 and the new remainder 73,and apply the division lemma to get

283 = 73 x 3 + 64

We consider the new divisor 73 and the new remainder 64,and apply the division lemma to get

73 = 64 x 1 + 9

We consider the new divisor 64 and the new remainder 9,and apply the division lemma to get

64 = 9 x 7 + 1

We consider the new divisor 9 and the new remainder 1,and apply the division lemma to get

9 = 1 x 9 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 639 and 995 is 1

Notice that 1 = HCF(9,1) = HCF(64,9) = HCF(73,64) = HCF(283,73) = HCF(356,283) = HCF(639,356) = HCF(995,639) .


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

Step 1: Since 392 > 1, we apply the division lemma to 392 and 1, to get

392 = 1 x 392 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 392 is 1

Notice that 1 = HCF(392,1) .


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

Step 1: Since 223 > 1, we apply the division lemma to 223 and 1, to get

223 = 1 x 223 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 223 is 1

Notice that 1 = HCF(223,1) .
