Given numbers are 671, 148, 639, 917
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(671, 148) = 99308
GCD(671, 148) = ( 671 x 148 ) / 99308
= 671 / 148
= 671
Step2:
LCM(1, 639) = 639
GCD(1, 639) = ( 1 x 639 ) / 639
= 1 / 639
= 1
Step3:
LCM(1, 917) = 917
GCD(1, 917) = ( 1 x 917 ) / 917
= 1 / 917
= 1
So, Greatest Common Divisor of 671, 148, 639, 917 is 1
