Given numbers are 180, 650, 688, 655
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(180, 650) = 11700
GCD(180, 650) = ( 180 x 650 ) / 11700
= 180 / 650
= 180
Step2:
LCM(10, 688) = 3440
GCD(10, 688) = ( 10 x 688 ) / 3440
= 10 / 688
= 10
Step3:
LCM(2, 655) = 1310
GCD(2, 655) = ( 2 x 655 ) / 1310
= 2 / 655
= 2
So, Greatest Common Divisor of 180, 650, 688, 655 is 1
