Given numbers are 478, 557, 139, 635
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(478, 557) = 266246
GCD(478, 557) = ( 478 x 557 ) / 266246
= 478 / 557
= 478
Step2:
LCM(1, 139) = 139
GCD(1, 139) = ( 1 x 139 ) / 139
= 1 / 139
= 1
Step3:
LCM(1, 635) = 635
GCD(1, 635) = ( 1 x 635 ) / 635
= 1 / 635
= 1
So, Greatest Common Divisor of 478, 557, 139, 635 is 1
