HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 136, 732, 649, 912 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 136, 732, 649, 912 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 136, 732, 649, 912 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 136, 732, 649, 912 is 1.
HCF(136, 732, 649, 912) = 1
HCF of 136, 732, 649, 912 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 136, 732, 649, 912 is 1.
Highest Common Factor of 136,732,649,912 is 1
Step 1: Since 732 > 136, we apply the division lemma to 732 and 136, to get
732 = 136 x 5 + 52
Step 2: Since the reminder 136 ≠ 0, we apply division lemma to 52 and 136, to get
136 = 52 x 2 + 32
Step 3: We consider the new divisor 52 and the new remainder 32, and apply the division lemma to get
52 = 32 x 1 + 20
We consider the new divisor 32 and the new remainder 20,and apply the division lemma to get
32 = 20 x 1 + 12
We consider the new divisor 20 and the new remainder 12,and apply the division lemma to get
20 = 12 x 1 + 8
We consider the new divisor 12 and the new remainder 8,and apply the division lemma to get
12 = 8 x 1 + 4
We consider the new divisor 8 and the new remainder 4,and apply the division lemma to get
8 = 4 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 136 and 732 is 4
Notice that 4 = HCF(8,4) = HCF(12,8) = HCF(20,12) = HCF(32,20) = HCF(52,32) = HCF(136,52) = HCF(732,136) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 649 > 4, we apply the division lemma to 649 and 4, to get
649 = 4 x 162 + 1
Step 2: Since the reminder 4 ≠ 0, we apply division lemma to 1 and 4, to get
4 = 1 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 4 and 649 is 1
Notice that 1 = HCF(4,1) = HCF(649,4) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 912 > 1, we apply the division lemma to 912 and 1, to get
912 = 1 x 912 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 912 is 1
Notice that 1 = HCF(912,1) .
