HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 577, 770, 69, 145 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 577, 770, 69, 145 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 577, 770, 69, 145 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 577, 770, 69, 145 is 1.

HCF(577, 770, 69, 145) = 1

Highest common factor (HCF) of 577, 770, 69, 145 is 1.

Highest Common Factor of 577,770,69,145 using Euclid's algorithm

Highest Common Factor of 577,770,69,145 is 1

Step 1: Since 770 > 577, we apply the division lemma to 770 and 577, to get

770 = 577 x 1 + 193

Step 2: Since the reminder 577 ≠ 0, we apply division lemma to 193 and 577, to get

577 = 193 x 2 + 191

Step 3: We consider the new divisor 193 and the new remainder 191, and apply the division lemma to get

193 = 191 x 1 + 2

We consider the new divisor 191 and the new remainder 2,and apply the division lemma to get

191 = 2 x 95 + 1

We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get

2 = 1 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 577 and 770 is 1

Notice that 1 = HCF(2,1) = HCF(191,2) = HCF(193,191) = HCF(577,193) = HCF(770,577) .


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

Step 1: Since 69 > 1, we apply the division lemma to 69 and 1, to get

69 = 1 x 69 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 69 is 1

Notice that 1 = HCF(69,1) .


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

Step 1: Since 145 > 1, we apply the division lemma to 145 and 1, to get

145 = 1 x 145 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 145 is 1

Notice that 1 = HCF(145,1) .
