Given numbers are 870, 640, 769, 986
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(870, 640) = 55680
GCD(870, 640) = ( 870 x 640 ) / 55680
= 870 / 640
= 870
Step2:
LCM(10, 769) = 7690
GCD(10, 769) = ( 10 x 769 ) / 7690
= 10 / 769
= 10
Step3:
LCM(1, 986) = 986
GCD(1, 986) = ( 1 x 986 ) / 986
= 1 / 986
= 1
So, Greatest Common Divisor of 870, 640, 769, 986 is 1
