Given numbers are 649, 157, 235, 856
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(649, 157) = 101893
GCD(649, 157) = ( 649 x 157 ) / 101893
= 649 / 157
= 649
Step2:
LCM(1, 235) = 235
GCD(1, 235) = ( 1 x 235 ) / 235
= 1 / 235
= 1
Step3:
LCM(1, 856) = 856
GCD(1, 856) = ( 1 x 856 ) / 856
= 1 / 856
= 1
So, Greatest Common Divisor of 649, 157, 235, 856 is 1
