Given numbers are 161, 668, 564, 657
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(161, 668) = 107548
GCD(161, 668) = ( 161 x 668 ) / 107548
= 161 / 668
= 161
Step2:
LCM(1, 564) = 564
GCD(1, 564) = ( 1 x 564 ) / 564
= 1 / 564
= 1
Step3:
LCM(1, 657) = 657
GCD(1, 657) = ( 1 x 657 ) / 657
= 1 / 657
= 1
So, Greatest Common Divisor of 161, 668, 564, 657 is 1
