Given numbers are 131, 153, 220, 286
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(131, 153) = 20043
GCD(131, 153) = ( 131 x 153 ) / 20043
= 131 / 153
= 131
Step2:
LCM(1, 220) = 220
GCD(1, 220) = ( 1 x 220 ) / 220
= 1 / 220
= 1
Step3:
LCM(1, 286) = 286
GCD(1, 286) = ( 1 x 286 ) / 286
= 1 / 286
= 1
So, Greatest Common Divisor of 131, 153, 220, 286 is 1
