Given numbers are 770, 620, 680, 783
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(770, 620) = 47740
GCD(770, 620) = ( 770 x 620 ) / 47740
= 770 / 620
= 770
Step2:
LCM(10, 680) = 680
GCD(10, 680) = ( 10 x 680 ) / 680
= 10 / 680
= 10
Step3:
LCM(10, 783) = 7830
GCD(10, 783) = ( 10 x 783 ) / 7830
= 10 / 783
= 10
So, Greatest Common Divisor of 770, 620, 680, 783 is 1
