GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(153, 478) = 73134
GCD(153, 478) = ( 153 x 478 ) / 73134
= 153 / 478
= 153
Step2:
LCM(1, 727) = 727
GCD(1, 727) = ( 1 x 727 ) / 727
= 1 / 727
= 1
Step3:
LCM(1, 215) = 215
GCD(1, 215) = ( 1 x 215 ) / 215
= 1 / 215
= 1
So, Greatest Common Divisor of 153, 478, 727, 215 is 1
