Given numbers are 125, 369, 646, 487
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(125, 369) = 46125
GCD(125, 369) = ( 125 x 369 ) / 46125
= 125 / 369
= 125
Step2:
LCM(1, 646) = 646
GCD(1, 646) = ( 1 x 646 ) / 646
= 1 / 646
= 1
Step3:
LCM(1, 487) = 487
GCD(1, 487) = ( 1 x 487 ) / 487
= 1 / 487
= 1
So, Greatest Common Divisor of 125, 369, 646, 487 is 1
