GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(215, 917) = 197155
GCD(215, 917) = ( 215 x 917 ) / 197155
= 215 / 917
= 215
Step2:
LCM(1, 365) = 365
GCD(1, 365) = ( 1 x 365 ) / 365
= 1 / 365
= 1
Step3:
LCM(1, 640) = 640
GCD(1, 640) = ( 1 x 640 ) / 640
= 1 / 640
= 1
So, Greatest Common Divisor of 215, 917, 365, 640 is 1
