Given numbers are 180, 280, 639, 175
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(180, 280) = 2520
GCD(180, 280) = ( 180 x 280 ) / 2520
= 180 / 280
= 180
Step2:
LCM(20, 639) = 12780
GCD(20, 639) = ( 20 x 639 ) / 12780
= 20 / 639
= 20
Step3:
LCM(1, 175) = 175
GCD(1, 175) = ( 1 x 175 ) / 175
= 1 / 175
= 1
So, Greatest Common Divisor of 180, 280, 639, 175 is 1
