HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 722, 975, 403 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 722, 975, 403 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 722, 975, 403 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 722, 975, 403 is 1.

HCF(722, 975, 403) = 1

Highest common factor (HCF) of 722, 975, 403 is 1.

Highest Common Factor of 722,975,403 using Euclid's algorithm

Highest Common Factor of 722,975,403 is 1

Step 1: Since 975 > 722, we apply the division lemma to 975 and 722, to get

975 = 722 x 1 + 253

Step 2: Since the reminder 722 ≠ 0, we apply division lemma to 253 and 722, to get

722 = 253 x 2 + 216

Step 3: We consider the new divisor 253 and the new remainder 216, and apply the division lemma to get

253 = 216 x 1 + 37

We consider the new divisor 216 and the new remainder 37,and apply the division lemma to get

216 = 37 x 5 + 31

We consider the new divisor 37 and the new remainder 31,and apply the division lemma to get

37 = 31 x 1 + 6

We consider the new divisor 31 and the new remainder 6,and apply the division lemma to get

31 = 6 x 5 + 1

We consider the new divisor 6 and the new remainder 1,and apply the division lemma to get

6 = 1 x 6 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 722 and 975 is 1

Notice that 1 = HCF(6,1) = HCF(31,6) = HCF(37,31) = HCF(216,37) = HCF(253,216) = HCF(722,253) = HCF(975,722) .

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

Step 1: Since 403 > 1, we apply the division lemma to 403 and 1, to get

403 = 1 x 403 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 403 is 1

Notice that 1 = HCF(403,1) .
