Given numbers are 620, 550, 220, 770
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(620, 550) = 34100
GCD(620, 550) = ( 620 x 550 ) / 34100
= 620 / 550
= 620
Step2:
LCM(10, 220) = 220
GCD(10, 220) = ( 10 x 220 ) / 220
= 10 / 220
= 10
Step3:
LCM(10, 770) = 770
GCD(10, 770) = ( 10 x 770 ) / 770
= 10 / 770
= 10
So, Greatest Common Divisor of 620, 550, 220, 770 is 10
