HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 949, 840, 661 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 949, 840, 661 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 949, 840, 661 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 949, 840, 661 is 1.

HCF(949, 840, 661) = 1

Highest common factor (HCF) of 949, 840, 661 is 1.

Highest Common Factor of 949,840,661 using Euclid's algorithm

Highest Common Factor of 949,840,661 is 1

Step 1: Since 949 > 840, we apply the division lemma to 949 and 840, to get

949 = 840 x 1 + 109

Step 2: Since the reminder 840 ≠ 0, we apply division lemma to 109 and 840, to get

840 = 109 x 7 + 77

Step 3: We consider the new divisor 109 and the new remainder 77, and apply the division lemma to get

109 = 77 x 1 + 32

We consider the new divisor 77 and the new remainder 32,and apply the division lemma to get

77 = 32 x 2 + 13

We consider the new divisor 32 and the new remainder 13,and apply the division lemma to get

32 = 13 x 2 + 6

We consider the new divisor 13 and the new remainder 6,and apply the division lemma to get

13 = 6 x 2 + 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 949 and 840 is 1

Notice that 1 = HCF(6,1) = HCF(13,6) = HCF(32,13) = HCF(77,32) = HCF(109,77) = HCF(840,109) = HCF(949,840) .

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

Step 1: Since 661 > 1, we apply the division lemma to 661 and 1, to get

661 = 1 x 661 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 661 is 1

Notice that 1 = HCF(661,1) .
