Given numbers are 605, 708, 280, 636
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(605, 708) = 428340
GCD(605, 708) = ( 605 x 708 ) / 428340
= 605 / 708
= 605
Step2:
LCM(1, 280) = 280
GCD(1, 280) = ( 1 x 280 ) / 280
= 1 / 280
= 1
Step3:
LCM(1, 636) = 636
GCD(1, 636) = ( 1 x 636 ) / 636
= 1 / 636
= 1
So, Greatest Common Divisor of 605, 708, 280, 636 is 1
