HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 736, 938, 861 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 736, 938, 861 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 736, 938, 861 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 736, 938, 861 is 1.
HCF(736, 938, 861) = 1
HCF of 736, 938, 861 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 736, 938, 861 is 1.
Highest Common Factor of 736,938,861 is 1
Step 1: Since 938 > 736, we apply the division lemma to 938 and 736, to get
938 = 736 x 1 + 202
Step 2: Since the reminder 736 ≠ 0, we apply division lemma to 202 and 736, to get
736 = 202 x 3 + 130
Step 3: We consider the new divisor 202 and the new remainder 130, and apply the division lemma to get
202 = 130 x 1 + 72
We consider the new divisor 130 and the new remainder 72,and apply the division lemma to get
130 = 72 x 1 + 58
We consider the new divisor 72 and the new remainder 58,and apply the division lemma to get
72 = 58 x 1 + 14
We consider the new divisor 58 and the new remainder 14,and apply the division lemma to get
58 = 14 x 4 + 2
We consider the new divisor 14 and the new remainder 2,and apply the division lemma to get
14 = 2 x 7 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 736 and 938 is 2
Notice that 2 = HCF(14,2) = HCF(58,14) = HCF(72,58) = HCF(130,72) = HCF(202,130) = HCF(736,202) = HCF(938,736) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 861 > 2, we apply the division lemma to 861 and 2, to get
861 = 2 x 430 + 1
Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, 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 2 and 861 is 1
Notice that 1 = HCF(2,1) = HCF(861,2) .
