Given numbers are 156, 538, 980, 165
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(156, 538) = 41964
GCD(156, 538) = ( 156 x 538 ) / 41964
= 156 / 538
= 156
Step2:
LCM(2, 980) = 980
GCD(2, 980) = ( 2 x 980 ) / 980
= 2 / 980
= 2
Step3:
LCM(2, 165) = 330
GCD(2, 165) = ( 2 x 165 ) / 330
= 2 / 165
= 2
So, Greatest Common Divisor of 156, 538, 980, 165 is 1
