Given numbers are 628, 262, 637, 221
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(628, 262) = 82268
GCD(628, 262) = ( 628 x 262 ) / 82268
= 628 / 262
= 628
Step2:
LCM(2, 637) = 1274
GCD(2, 637) = ( 2 x 637 ) / 1274
= 2 / 637
= 2
Step3:
LCM(1, 221) = 221
GCD(1, 221) = ( 1 x 221 ) / 221
= 1 / 221
= 1
So, Greatest Common Divisor of 628, 262, 637, 221 is 1
