HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 669, 946, 120, 27 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 669, 946, 120, 27 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 669, 946, 120, 27 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 669, 946, 120, 27 is 1.

HCF(669, 946, 120, 27) = 1

Highest common factor (HCF) of 669, 946, 120, 27 is 1.

Highest Common Factor of 669,946,120,27 using Euclid's algorithm

Highest Common Factor of 669,946,120,27 is 1

Step 1: Since 946 > 669, we apply the division lemma to 946 and 669, to get

946 = 669 x 1 + 277

Step 2: Since the reminder 669 ≠ 0, we apply division lemma to 277 and 669, to get

669 = 277 x 2 + 115

Step 3: We consider the new divisor 277 and the new remainder 115, and apply the division lemma to get

277 = 115 x 2 + 47

We consider the new divisor 115 and the new remainder 47,and apply the division lemma to get

115 = 47 x 2 + 21

We consider the new divisor 47 and the new remainder 21,and apply the division lemma to get

47 = 21 x 2 + 5

We consider the new divisor 21 and the new remainder 5,and apply the division lemma to get

21 = 5 x 4 + 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 669 and 946 is 1

Notice that 1 = HCF(5,1) = HCF(21,5) = HCF(47,21) = HCF(115,47) = HCF(277,115) = HCF(669,277) = HCF(946,669) .


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

Step 1: Since 120 > 1, we apply the division lemma to 120 and 1, to get

120 = 1 x 120 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 120 is 1

Notice that 1 = HCF(120,1) .


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

Step 1: Since 27 > 1, we apply the division lemma to 27 and 1, to get

27 = 1 x 27 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 27 is 1

Notice that 1 = HCF(27,1) .
