Given numbers are 877, 478, 102, 221
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(877, 478) = 419206
GCD(877, 478) = ( 877 x 478 ) / 419206
= 877 / 478
= 877
Step2:
LCM(1, 102) = 102
GCD(1, 102) = ( 1 x 102 ) / 102
= 1 / 102
= 1
Step3:
LCM(1, 221) = 221
GCD(1, 221) = ( 1 x 221 ) / 221
= 1 / 221
= 1
So, Greatest Common Divisor of 877, 478, 102, 221 is 1
