GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(428, 247) = 105716
GCD(428, 247) = ( 428 x 247 ) / 105716
= 428 / 247
= 428
Step2:
LCM(1, 379) = 379
GCD(1, 379) = ( 1 x 379 ) / 379
= 1 / 379
= 1
Step3:
LCM(1, 532) = 532
GCD(1, 532) = ( 1 x 532 ) / 532
= 1 / 532
= 1
So, Greatest Common Divisor of 428, 247, 379, 532 is 1
