Given numbers are 495, 420, 755, 428
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(495, 420) = 13860
GCD(495, 420) = ( 495 x 420 ) / 13860
= 495 / 420
= 495
Step2:
LCM(15, 755) = 2265
GCD(15, 755) = ( 15 x 755 ) / 2265
= 15 / 755
= 15
Step3:
LCM(5, 428) = 2140
GCD(5, 428) = ( 5 x 428 ) / 2140
= 5 / 428
= 5
So, Greatest Common Divisor of 495, 420, 755, 428 is 1
