Given numbers are 639, 315, 542, 148
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(639, 315) = 22365
GCD(639, 315) = ( 639 x 315 ) / 22365
= 639 / 315
= 639
Step2:
LCM(9, 542) = 4878
GCD(9, 542) = ( 9 x 542 ) / 4878
= 9 / 542
= 9
Step3:
LCM(1, 148) = 148
GCD(1, 148) = ( 1 x 148 ) / 148
= 1 / 148
= 1
So, Greatest Common Divisor of 639, 315, 542, 148 is 1
