HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 392, 639, 904 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 392, 639, 904 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 392, 639, 904 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 392, 639, 904 is 1.

HCF(392, 639, 904) = 1

Highest common factor (HCF) of 392, 639, 904 is 1.

Highest Common Factor of 392,639,904 using Euclid's algorithm

Highest Common Factor of 392,639,904 is 1

Step 1: Since 639 > 392, we apply the division lemma to 639 and 392, to get

639 = 392 x 1 + 247

Step 2: Since the reminder 392 ≠ 0, we apply division lemma to 247 and 392, to get

392 = 247 x 1 + 145

Step 3: We consider the new divisor 247 and the new remainder 145, and apply the division lemma to get

247 = 145 x 1 + 102

We consider the new divisor 145 and the new remainder 102,and apply the division lemma to get

145 = 102 x 1 + 43

We consider the new divisor 102 and the new remainder 43,and apply the division lemma to get

102 = 43 x 2 + 16

We consider the new divisor 43 and the new remainder 16,and apply the division lemma to get

43 = 16 x 2 + 11

We consider the new divisor 16 and the new remainder 11,and apply the division lemma to get

16 = 11 x 1 + 5

We consider the new divisor 11 and the new remainder 5,and apply the division lemma to get

11 = 5 x 2 + 1

We consider the new divisor 5 and the new remainder 1,and apply the division lemma to get

5 = 1 x 5 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 392 and 639 is 1

Notice that 1 = HCF(5,1) = HCF(11,5) = HCF(16,11) = HCF(43,16) = HCF(102,43) = HCF(145,102) = HCF(247,145) = HCF(392,247) = HCF(639,392) .

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

Step 1: Since 904 > 1, we apply the division lemma to 904 and 1, to get

904 = 1 x 904 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 904 is 1

Notice that 1 = HCF(904,1) .
