Given numbers are 781, 427, 197, 358
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(781, 427) = 333487
GCD(781, 427) = ( 781 x 427 ) / 333487
= 781 / 427
= 781
Step2:
LCM(1, 197) = 197
GCD(1, 197) = ( 1 x 197 ) / 197
= 1 / 197
= 1
Step3:
LCM(1, 358) = 358
GCD(1, 358) = ( 1 x 358 ) / 358
= 1 / 358
= 1
So, Greatest Common Divisor of 781, 427, 197, 358 is 1
