Given numbers are 155, 747, 285, 936
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(155, 747) = 115785
GCD(155, 747) = ( 155 x 747 ) / 115785
= 155 / 747
= 155
Step2:
LCM(1, 285) = 285
GCD(1, 285) = ( 1 x 285 ) / 285
= 1 / 285
= 1
Step3:
LCM(1, 936) = 936
GCD(1, 936) = ( 1 x 936 ) / 936
= 1 / 936
= 1
So, Greatest Common Divisor of 155, 747, 285, 936 is 1
