Given numbers are 546, 721, 215, 639
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(546, 721) = 56238
GCD(546, 721) = ( 546 x 721 ) / 56238
= 546 / 721
= 546
Step2:
LCM(7, 215) = 1505
GCD(7, 215) = ( 7 x 215 ) / 1505
= 7 / 215
= 7
Step3:
LCM(1, 639) = 639
GCD(1, 639) = ( 1 x 639 ) / 639
= 1 / 639
= 1
So, Greatest Common Divisor of 546, 721, 215, 639 is 1
