Given numbers are 544, 669, 680, 840
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(544, 669) = 363936
GCD(544, 669) = ( 544 x 669 ) / 363936
= 544 / 669
= 544
Step2:
LCM(1, 680) = 680
GCD(1, 680) = ( 1 x 680 ) / 680
= 1 / 680
= 1
Step3:
LCM(1, 840) = 840
GCD(1, 840) = ( 1 x 840 ) / 840
= 1 / 840
= 1
So, Greatest Common Divisor of 544, 669, 680, 840 is 1
