Given numbers are 782, 266, 220, 655
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(782, 266) = 104006
GCD(782, 266) = ( 782 x 266 ) / 104006
= 782 / 266
= 782
Step2:
LCM(2, 220) = 220
GCD(2, 220) = ( 2 x 220 ) / 220
= 2 / 220
= 2
Step3:
LCM(2, 655) = 1310
GCD(2, 655) = ( 2 x 655 ) / 1310
= 2 / 655
= 2
So, Greatest Common Divisor of 782, 266, 220, 655 is 1
