Given numbers are 427, 524, 861, 124
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(427, 524) = 223748
GCD(427, 524) = ( 427 x 524 ) / 223748
= 427 / 524
= 427
Step2:
LCM(1, 861) = 861
GCD(1, 861) = ( 1 x 861 ) / 861
= 1 / 861
= 1
Step3:
LCM(1, 124) = 124
GCD(1, 124) = ( 1 x 124 ) / 124
= 1 / 124
= 1
So, Greatest Common Divisor of 427, 524, 861, 124 is 1
