Given numbers are 655, 990, 162, 417
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(655, 990) = 129690
GCD(655, 990) = ( 655 x 990 ) / 129690
= 655 / 990
= 655
Step2:
LCM(5, 162) = 810
GCD(5, 162) = ( 5 x 162 ) / 810
= 5 / 162
= 5
Step3:
LCM(1, 417) = 417
GCD(1, 417) = ( 1 x 417 ) / 417
= 1 / 417
= 1
So, Greatest Common Divisor of 655, 990, 162, 417 is 1
