Prime factors of 161 are 7 x 23
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 840, 772, 662, 161
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(840, 772) = 162120
GCD(840, 772) = ( 840 x 772 ) / 162120
= 840 / 772
= 840
Step2:
LCM(4, 662) = 1324
GCD(4, 662) = ( 4 x 662 ) / 1324
= 4 / 662
= 4
Step3:
LCM(2, 161) = 322
GCD(2, 161) = ( 2 x 161 ) / 322
= 2 / 161
= 2
So, Greatest Common Divisor of 840, 772, 662, 161 is 1
