Given numbers are 420, 707, 382, 531
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(420, 707) = 42420
GCD(420, 707) = ( 420 x 707 ) / 42420
= 420 / 707
= 420
Step2:
LCM(7, 382) = 2674
GCD(7, 382) = ( 7 x 382 ) / 2674
= 7 / 382
= 7
Step3:
LCM(1, 531) = 531
GCD(1, 531) = ( 1 x 531 ) / 531
= 1 / 531
= 1
So, Greatest Common Divisor of 420, 707, 382, 531 is 1
