Given numbers are 280, 620, 624, 430
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(280, 620) = 8680
GCD(280, 620) = ( 280 x 620 ) / 8680
= 280 / 620
= 280
Step2:
LCM(20, 624) = 3120
GCD(20, 624) = ( 20 x 624 ) / 3120
= 20 / 624
= 20
Step3:
LCM(4, 430) = 860
GCD(4, 430) = ( 4 x 430 ) / 860
= 4 / 430
= 4
So, Greatest Common Divisor of 280, 620, 624, 430 is 2
