Given numbers are 680, 705, 741, 620
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(680, 705) = 95880
GCD(680, 705) = ( 680 x 705 ) / 95880
= 680 / 705
= 680
Step2:
LCM(5, 741) = 3705
GCD(5, 741) = ( 5 x 741 ) / 3705
= 5 / 741
= 5
Step3:
LCM(1, 620) = 620
GCD(1, 620) = ( 1 x 620 ) / 620
= 1 / 620
= 1
So, Greatest Common Divisor of 680, 705, 741, 620 is 1
