Given numbers are 546, 620, 818, 139
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(546, 620) = 169260
GCD(546, 620) = ( 546 x 620 ) / 169260
= 546 / 620
= 546
Step2:
LCM(2, 818) = 818
GCD(2, 818) = ( 2 x 818 ) / 818
= 2 / 818
= 2
Step3:
LCM(2, 139) = 278
GCD(2, 139) = ( 2 x 139 ) / 278
= 2 / 139
= 2
So, Greatest Common Divisor of 546, 620, 818, 139 is 1
