HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 379, 986 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 379, 986 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 379, 986 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 379, 986 is 1.

HCF(379, 986) = 1

Highest Common Factor of 379,986 using Euclid's algorithm

Highest Common Factor of 379,986 is 1

Step 1: Since 986 > 379, we apply the division lemma to 986 and 379, to get

986 = 379 x 2 + 228

Step 2: Since the reminder 379 ≠ 0, we apply division lemma to 228 and 379, to get

379 = 228 x 1 + 151

Step 3: We consider the new divisor 228 and the new remainder 151, and apply the division lemma to get

228 = 151 x 1 + 77

We consider the new divisor 151 and the new remainder 77,and apply the division lemma to get

151 = 77 x 1 + 74

We consider the new divisor 77 and the new remainder 74,and apply the division lemma to get

77 = 74 x 1 + 3

We consider the new divisor 74 and the new remainder 3,and apply the division lemma to get

74 = 3 x 24 + 2

We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get

3 = 2 x 1 + 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 379 and 986 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(74,3) = HCF(77,74) = HCF(151,77) = HCF(228,151) = HCF(379,228) = HCF(986,379) .
