Given numbers are 247, 266, 156, 357
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(247, 266) = 3458
GCD(247, 266) = ( 247 x 266 ) / 3458
= 247 / 266
= 247
Step2:
LCM(19, 156) = 2964
GCD(19, 156) = ( 19 x 156 ) / 2964
= 19 / 156
= 19
Step3:
LCM(1, 357) = 357
GCD(1, 357) = ( 1 x 357 ) / 357
= 1 / 357
= 1
So, Greatest Common Divisor of 247, 266, 156, 357 is 1
